This amendment to Texas Instruments Incorporated (the "Registrant") Form 8-K 
dated December 24, 1997 is being filed to provide the information required by 
Item 7, Financial Statements and Pro Forma Financial Information, which 
pursuant to Item 7(a)(4) of Form 8-K permits the Registrant to file the 
required financial statements of the business acquired and pro forma 
financial information within 60 days of the due date of the original Form 8-K.


ITEM 2.  Acquisition or Disposition of Assets.

         As previously announced, an Agreement and Plan of Merger (the "Merger 
Agreement") by and among Texas Instruments Incorporated, a Delaware corporation
(the "Company"), DSL Acquisition Corporation, a Delaware corporation and 
wholly-owned subsidiary of the Company (the "Sub"), and Amati Communications 
Corporation, a Delaware corporation ("Amati"), was entered into on November 19,
1997. Pursuant to the Merger Agreement, Sub commenced on November 25, 1997 a 
tender offer (the "Offer") for all outstanding shares of Common Stock of Amati 
(the "Shares") at a price of $20.00 per share, net to the seller in cash, 
without interest.  The Offer expired at 12:00 midnight, New York City time, 
on December 23, 1997.  Following the expiration of the Offer, Sub accepted 
for payment 15,290,381 Shares (approximately 77.0% of the issued and 
outstanding Shares) validly tendered and not withdrawn pursuant to the 
Offer, which number gives effect to the failure of a number of Shares of 
Common Stock to be delivered in accordance with guaranteed delivery 
procedures.

        On February 27, 1998, pursuant to the terms and conditions of the 
Merger Agreement, Sub was merged with and into Amati such that Amati became 
a wholly-owned subsidiary of the Company, and Sub ceased to exist as an 
independent entity (the "Merger").  Each Share issued and outstanding 
immediately prior to the Effective Time (as defined in the Merger Agreement)
(other than Shares owned by the Company, Sub or any wholly-owned subsidiary 
of the Company, or Shares held by dissenting stockholders who properly 
exercised and perfected their appraisal rights under Section 262 of the 
General Corporation Law of the State of Delaware) was, by virtue of the 
Merger, converted into the right to receive $20.00 in cash.  Each Share held 
by the Company, Sub or any wholly-owned subsidiary of the Company immediately 
prior to the Effective Time was, by virtue of the merger, cancelled and 
retired and ceased to exist.  Simultaneously, each share of the common stock, 
par value $.01 per share, of Sub was, by virtue of the Merger, converted into 
one share of the common stock of Amati.  Accordingly, the Company owns 1,000 
shares of the common stock of Amati, which is 100% of the outstanding common 
stock thereof.  A press release relating to the foregoing is filed as Exhibit 
99.2 hereto and is incorporated by reference herein.

Audited Financial Information
Amati Communications Corporation Consolidated Balance 
Sheets as of August 2, 1997 and July 27, 1996, and 
Consolidated Statements of Operations, Stockholders'
Equity and Cash Flows for the three years ended August 
2, 1997, July 27, 1996, and July 29, 1995.


                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To the Board of Directors of Amati Communications Corporation:
 
    We have audited the accompanying consolidated balance sheets of Amati
Communications Corporation (a Delaware corporation) and subsidiaries as of
August 2, 1997 and July 27, 1996, and the related consolidated statements of
operations, stockholders' equity and cash flows for each of the three years
ended August 2, 1997, July 27, 1996, and July 29, 1995. These financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.
 
    We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
    In our opinion, the financial statements referred to above present fairly,
on all material respects, the financial position of Amati Communications
Corporation and subsidiaries as of August 2, 1997 and July 27, 1996, and the
results of their operations and their cash flows for each of the three years
ended August 2, 1997, July 27, 1996, and July 29, 1995 in conformity with
generally accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
  
                                 AUGUST 2, 1997
 
NOTE 1  OPERATIONS, LIQUIDITY AND PROPOSED MERGER OF THE COMPANY
 
OPERATIONS
 
    Amati Communications Corporation ("Amati" or the "Company") is a leading
developer of advanced transmission equipment utilizing Discrete Multi-tone
("DMT") technology for the Asymmetrical Digital Subscriber Line ("ADSL"), Very
high-speed Digital Subscriber Line ("VDSL") and cable modem markets. The Company
is the holder of the ADSL/DMT patents and has licensed the technology to
companies such as Motorola, NEC, Nortel and Analog Devices, Inc. The Company is
also a provider of network connectivity systems for the internetworking and OEM
marketplaces, which include local area network gateways, client-based
workstation software and network data communications interfaces. The Company is
subject to a number of risks, including dependence on key employees for
technology development and support, dependence on a few significant customers,
potential competition from larger more established companies, and its ability to
obtain adequate financing to support its growth.
 
    On November 28, 1995, the Company and Amati Communications Corporation ("Old
Amati"), a privately held Mountain View, California based company completed a
merger (the "Merger") by which Old Amati became a wholly-owned subsidiary of the
Company. Effective as of the Merger, the Company's name was changed to Amati
Communications Corporation and its common stock began trading on the Nasdaq
National Market under the symbol "AMTX".
 
LIQUIDITY
 
    In October 1996, the Company entered into an Investment Agreement (the
"Investment Agreement") with Quantum Industrial Partners LDC, S-C Phoenix
Holdings, L.L.C., Winston Partners, L.P., Winston Partners II LDC and Winston
Partners II L.L.C. (collectively, the "Investors") which provided to the Company
$15 million in equity financing in exchange for the issuance of Company's Common
Stock and warrants (the "Warrants") to purchase up to 600,000 shares of
Company's Common Stock. The Warrants were issued on October 3, 1996 and are
exercisable at any time between December 17, 1996 and December 17, 2001.
Warrants to purchase up to 300,000 shares are exercisable at $17.45 per share;
Warrants to purchase the other 300,000 shares are exercisable at $25 per share.
 
    As of August 2, 1997, the Company has received $12,500,000 pursuant to this
Investment Agreement and recorded a Stock Subscription Receivable of $2,500,000.
In exchange for the $15,000,000 investment in the Company, the Investors
received an aggregate of 1,242,915 shares of the Company's Common Stock. The
Warrants and Common Stock issued in connection with the Investment Agreement
were exempt from the registration requirements of the Securities Act of 1933, as
amended (the "Securities Act"), pursuant to the exemption under Section 4(2) of
the Securities Act. The resale of the shares of Common Stock issued to the
Investors, and the 600,000 shares of Common Stock issuable on exercise of the
Warrants, has been registered by the Company on behalf of the Investors. On
August 7, 1997, the Company received the final $2,500,000 take down in equity
financing.
 
    The Company's ability to meet its future capital requirements will depend on
many factors, including sales levels, progress in research and development
programs, the establishment of collaborative agreements, and costs of
manufacturing facilities and commercialization activities. While the Company
anticipates that the funding available under the line of credit, capital lease
line and a loan agreement entered into with Westell Technologies, Inc. (further
discussed) will be sufficient to meet its capital requirements through the
fiscal year, the Company may require funding in addition to that available under
these

NOTE 2  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
CONSOLIDATION
 
    The consolidated financial statements include the accounts of the Company
and its wholly-owned subsidiaries. All significant intercompany accounts and
transactions have been eliminated.
 
INVENTORIES
 
    Inventories are stated at the lower of cost (first-in, first-out) or market,
and include materials, labor and manufacturing overhead. Inventory is valued at
currently adjusted standards which approximate actual costs on a first-in,
first-out basis.
 
DEPRECIATION AND AMORTIZATION
 
    Depreciation and amortization are provided using the straight-line method
over the estimated useful lives of the related assets. Machinery and equipment
and furniture and fixtures generally have lives ranging from 3 to 5 years.
Leasehold improvements are depreciated over the shorter of the lease term or the
useful life.
 
SOFTWARE DEVELOPMENT COSTS
 
    The Company capitalizes software development costs in accordance with
Statement of Financial Accounting Standards No. 86 ("SFAS 86"). The
capitalization of these costs begins when technological feasibility of the
related product has been achieved, which has been defined as the point in time
that the Company has developed a beta version of the software product.
Capitalization ends when the product is

available for general release to customers. Amortization is computed on an
individual product basis and is the greater of (a) the ratio of current gross
revenues for a product to the total current and anticipated future gross
revenues for that product or (b) the straight-line method over the estimated
economic life of the product. Currently the Company is using an estimated
economic life of three years for all capitalized software costs.
 
    In fiscal 1995, 1996 and 1997, there was no capitalization of software
development costs as the criteria for capitalization had not been met.
Amortization of capitalized software development costs charged to cost of sales
was $310,000 in fiscal 1995 and $246,000 in fiscal 1996 and 1997.

</TABLE>
 
REVENUE RECOGNITION
 
    The Company generally recognizes revenue from product sales upon shipment to
the customer. Revenues from software and engineering development services are
recognized as the Company performs the services in accordance with contract
terms. Revenues from maintenance and extended warranty agreements are recognized
ratably over the term of the agreement. The Company also licenses products to
OEMs and recognizes royalties as specified in the license agreement when
shipment of the licensed product by the OEM is reported to the Company. Service
maintenance, warranty and support revenues accounted for less than 1% of the
Company's total revenues.
 
SUPPLEMENTAL DISCLOSURES OF CASH FLOW INFORMATION
 
    For purposes of the Statements of Cash Flows, cash and cash equivalents are
defined as cash in banks and highly liquid investments with original maturity
dates of three months or less.
 
    Capital lease obligations of $3,307,000 were incurred in fiscal 1997 when
the Company entered into equipment and furniture capital leases. Cash paid for
interest was $7,000, $56,000 and $317,000 for the fiscal years 1995, 1996 and
1997, respectively. Cash paid for income taxes were $20,000, $73,000 and $46,000
for fiscal years 1995, 1996 and 1997, respectively.
 
SHORT TERM INVESTMENTS
 
    In accordance with SFAS No. 115, the Company has classified all of its
marketable debt securities as held-to-maturity, and has accounted for these
investments at amortized cost. Accordingly, no adjustment for unrealized holding
gains or losses has been reflected in the Company's financial statements. At
August 2, 1997, the Company's held-to-maturity securities of $709,000 consisted
of certificates of deposits

with contractual maturities of less than twelve months and the carrying amount
of these investments approximated market value. These funds, in the form of
standby letters of credit, are restricted as a compensating balance for capital
lease not under the lease line.
 
FUNDED DEVELOPMENT AGREEMENTS
 
    The Company has entered into certain funded development arrangements with
IBM. These arrangement typically provide funding to the Company to develop on a
best efforts basis certain products or product enhancements which IBM is
interested in reselling to its customers. Under these arrangements, the Company
retains the rights to manufacture the developed products and IBM purchases the
manufactured products from the Company for distribution to IBM's customers. The
arrangements typically include a minimum purchase commitment by IBM if the
development is successful. Costs under these agreements are deferred until the
related development revenues are recognized. Revenues under these agreements are
generally recognized when certain contractual milestones are met. Total revenues
recognized under these agreements were $276,000, $419,000 and $341,000 in fiscal
1995, 1996 and 1997, respectively.
 
USE OF ESTIMATES IN THE PREPARATION OF FINANCIAL STATEMENTS
 
    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the period.
Actual results could differ from those estimates.
 
LONG-LIVED ASSETS
 
    Effective July 28, 1996, the Company adopted Statement of financial
Accounting Standards No. 121 ("SFAS No. 121"), ACCOUNTING FOR THE IMPAIRMENT OF
LONG-LIVED ASSETS AND FOR LONG-LIVED ASSETS TO BE DISPOSED OF. The adoption of
SFAS No. 121 did not have a material impact on the results of operations or the
financial position of the Company.
 
STOCK COMPENSATION
 
    Effective July 28, 1996, the Company adopted the disclosure provisions of
Statement of Financial Accounting Standards No. 123 ("SFAS No. 123"), ACCOUNTING
FOR STOCK-BASED COMPENSATION. In accordance with the provisions of SFAS No. 123,
the Company applies APB Opinion 25 and related interpretations in accounting for
its stock option plans. Note 6 of these Consolidated Financial Statements
contains a summary of the pro forma effects on reported net income and earnings
per share for fiscal 1997 and 1996 based on the fair value of the options
granted at grant date as prescribed by SFAS No. 123.
 
RECENT ACCOUNTING PRONOUNCEMENTS
 
    In June 1997, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards No. 130 ("SFAS No. 130"), REPORTING
COMPREHENSIVE INCOME, which becomes effective for fiscal years beginning after
December 15, 1997. The adoption of SFAS No. 130 is not expected to have a
material impact on the results of operations or the financial position of the
Company.

    Also in June 1997, the FASB issued Statement of Financial Accounting
Standards No. 131 ("SFAS No. 131"), DISCLOSURES ABOUT SEGMENTS OF AN ENTERPRISE

after December 15, 1997. The Company has yet to determine the impact, if any, of
adoption of this new pronouncement.
 
RECLASSIFICATION
 
    Prior years' amounts in the Consolidated Financial Statements have been
reclassified where necessary to conform to the fiscal 1997 presentation.
 
NOTE 3  CONCENTRATIONS OF CREDIT RISK AND MAJOR CUSTOMERS
 
    Financial instruments which may potentially subject the Company to a
concentration of credit risk principally consist of accounts receivable. The
Company generally does not require collateral on accounts receivable as the
majority of the Company's customers are large, well established companies.
 
    Sales of the Overture 4 and Overture 8 series of ADSL transceivers were
$999,000 and $819,000, respectively, in fiscal 1996 and $12,000 and $1,880,000,
respectively, in fiscal 1997. In the Company's VDSL technology, revenues
recognized during the current fiscal year of $3,500,000 related primarily to
contract revenues under a joint development agreement with NEC Japan.
 
    The Company also designs, manufactures and markets data communications
equipment and provides technical support and maintenance services related
thereto. Sales to IBM as a percent of net sales were 83%, 69% and 51% in fiscal
1995, 1996 and 1997, respectively. The Company has a concentration of accounts
receivable with IBM of $600,000 as of August 2, 1997. In February 1997, the
Company signed an extended contract with IBM for the development and manufacture
of its next generation internetworking products. The Company expects that IBM
will continue to account for a substantial portion of its revenues until
development and commercialization of its ADSL products are completed.
 
    Export sales of connectivity products, primarily to Western Europe and
Canada in fiscal 1995, 1996 and 1997, represented 1-2% of total net sales.
Shipments of the Overture series of transceivers primarily to the countries of
Germany, Netherlands, France, Finland and Canada accounted for 11% of total
revenues in fiscal 1997.
 
NOTE 4  LICENSE AGREEMENTS
 
    The Company has certain license agreements (the "Original Agreements") with
Stanford University and University Ventures II, a California limited investment
partnership, whereby it was granted exclusive worldwide rights to core
technology and was required to further develop commercial applications and
licensed products in the field of use to maintain these agreements. In exchange
for the Original Agreements, the Company agreed to issue 125,000 shares of
Series A convertible preferred stock to each licensor and pay certain royalties
on revenue generated from the licensed technology. Both Original Agreements
contained anti-dilution provisions in the event the Company raised capital from
the sale of stock. The term of the Original Agreements extends to the last
expiration date of the licensed patents. The Company accounted for the license
agreements as a transfer of non-monetary assets from its founders and recorded
the license at the transferor's historical cost basis of zero. On May 1, 1994,
the Original Agreement with Stanford University was revised to include a
one-time fee of $250,000 and an annual

NOTE 4  LICENSE AGREEMENTS (CONTINUED)
license maintenance fee of $25,000. The revised Original Agreements provide for
Stanford University to receive higher royalties on the Company's revenues.
Stanford University may terminate the agreement if the Company fails to remedy
any conditions causing default, breach or incorrect reporting under the terms
and conditions of the license agreement within thirty days.
 
NOTE 5  NOTES PAYABLE
 
    The Company had notes payable in the amount of $395,000 at July 27, 1996.
All outstanding notes of $395,000 plus interest of $103,000 were paid on January
31, 1997.
 
    The Company has a revolving line of credit agreement with a bank which
expires on April 25, 1998. The agreement provides for borrowings up to
$2,000,000 at the bank's prime rate plus .75% (9.25 % at August 2, 1997). The
line of credit is collateralized by the accounts receivable of the Company. As
of August 2, 1997, borrowings under this agreement were $428,000. Borrowings
under this agreement are subject to certain debt covenants. At August 2, 1997,
the Company was out of compliance with certain of these covenants relating to
quick ratios and debt to net worth ratios. Acknowledging however, that with the
$2,500,000 of cash received on August 7, 1997 from stock subscriptions
receivable shown on the balance sheet as of fiscal 1997 year-end the Company
will be in compliance, the bank waived all financial covenants in default. In
addition, the Company has a capital lease line of $1,700,000 which was fully
utilized as of August 2, 1997.
 
NOTE 6  STOCK OPTION PLANS
 
    The Company has four employees' and one non-employee Directors' stock option
plans. The exercise price of options granted under any plan may not be less than
100% of the fair market value of the stock on the date of grant.
 
    An Incentive Stock Option Plan and a Supplemental Stock Option Plan were
adopted by the Company in 1981. Total shares authorized for issuance pursuant to
the Incentive Stock Option Plan and the Supplemental Stock Option Plan were
875,000 shares and 1,025,000 shares, respectively. As of August 2, 1997, options
to purchase up to 30,000 shares have been granted pursuant to these plans and
remain exercisable, and there are no options available for future grant under
these plans. Employee stock options issued under this plan become exercisable at
the rate of 25% after six months from the date of grant and 25% per year
thereafter, unless determined otherwise by the Board of Directors at the time of
grant. Both plans expired in October 1991. The options that have been granted
under these plans expire ten years after grant.
 
    The Board of Directors adopted the 1990 Stock Option Plan on September 14,
1990, and it was approved by the Company's stockholders on December 14, 1990.
The Company is authorized to issue options to purchase up to 900,000 shares of
Company Common Stock pursuant to the 1990 Stock Option Plan. At a special
meeting of the Company's stockholders held on November 10, 1995, the
stockholders approved an amendment to the Company's 1990 Stock Option Plan to
increase the number of shares available for issuance pursuant to this plan in
conjunction with the Agreement of Merger dated August 3, 1995. The Company may
now issue options to purchase an aggregate of up to 3,500,000 shares pursuant to
the amended 1990 Stock Option Plan. As of August 2, 1997, options to purchase up
to 2,946,686 shares have been granted pursuant to this plan, of which options to

NOTE 6  STOCK OPTION PLANS (CONTINUED)
exercisable on such date and 3,664 shares were available for future grant under
this plan. Employee stock options issued pursuant to this plan become
exercisable at the rate of 25% one year from the date of the Merger and 25% per
year thereafter. The maximum term of options granted under this plan is ten
years.
 
    The Old Amati 1992 Stock Option Plan and all outstanding and unexercised
options issued pursuant thereto were assumed by the Company upon consummation of
the merger, as approved by the stockholders of the Company on November 20, 1995.
The Company is authorized to grant options of 1,591,234 shares of Company Common
Stock pursuant to this plan. As of August 2, 1997, options to purchase up to
743,051 shares of Company Common Stock have been granted, pursuant to this plan,
including options to purchase up to 317,405 shares which were exercisable as of
such date. There are no shares available for future grants under this plan.
Employee stock options under this plan become exercisable at the rate of 25% one
year from the date of grant and with respect to 1/48 of the number of shares
subject to such option each month thereafter.
 
    On July 12, 1996, the Company adopted the 1996 Stock Option Plan, and
authorized 1,000,000 shares of Company Common Stock. As of August 2, 1997,
options to purchase up to 950,000 shares have been granted, of which options to
purchase up to 314,125 shares were exercisable as of such date and 50,000 shares
were available for future grants under this plan.
 
    The Company adopted a 1990 Non-Employee Directors' Stock Option Plan on
September 14, 1990, which was approved by the Company's stockholders on December
14, 1990. The Company is authorized to issue options to purchase up to an
aggregate of 395,000 shares of the Company's Common Stock pursuant to this plan.
On the date the plan was adopted, each non-employee Director then in office was
granted an option to purchase up to 25,000 shares of Common Stock of the
Company. Each person who is elected for the first time to be a non-employee
Director will automatically be granted an option to purchase 25,000 shares of
the Company's Common Stock pursuant to this plan, which options will be
immediately exercisable. On December 2, 1993, the plan was amended to reduce by
150,000 shares the number of shares available for issuance pursuant to the plan,
leaving 245,000 shares available for grant under this plan. As of August 2,
1997, options to purchase up to 102,500 shares have been granted pursuant to
this plan, of which options to purchase up to 80,000 shares were exercisable as
of such date and 25,000 shares were available for future grants under this plan.
On September 1 of each year commencing September 1, 1991, an option to purchase
10,000 shares of the Company's common stock are automatically granted to each
non-employee Director then in office. Beginning with grants made to each
continuing non-employee Director in office on September 1, 1996, each person
shall receive an option to purchase up to 20,000 shares of the Company's Common
Stock. Grants are automatically made annually under this plan. These options
become exercisable at the rate of 25% after six months from the date of grant
and 25% per year thereafter. These options expire ten years after grant.
 
    In accordance with the disclosure requirements of SFAS No. 123, if the
Company had elected to recognize compensation cost based on the fair value of
the options granted at grant date as prescribed, income and earnings per share
would have been reduced to the pro forma amounts indicated in the table below.
The pro forma effect on net income for fiscal 1996 and 1997 is not

NOTE 7  INCOME TAXES
 
    As of August 2, 1997, the Company's tax net operating loss carryforwards for
federal tax purposes were approximately $45,066,000. The United States Tax
Reform Act of 1986 contains provisions which limit the amount of net operating
loss carryforwards which may be utilized in any given fiscal year when a
significant change in ownership interest occurs. These carryforwards expire in
various amounts through fiscal 2012. The Company also has certain tax credit
carryforwards of $1,650,000 which expire in various amounts through the year
2012. The United States Tax Reform Act of 1986 contains provisions that may
limit the net operating loss carryforwards and research and development credits
available to be used in any given year should certain events occur.
 
    The Company has an additional $2,234,000 of net operating loss carryforwards
which were acquired in connection with a fiscal 1988 acquisition. The change in
ownership of the acquired company will affect the availability and timing of the
amount of prior losses to be used to offset taxable income in future years.
These carryforwards expire in various amounts through the year 2005.
 
    As of August 2, 1997, the Company also has net operating loss carryforwards
of approximately $10,000,000 available to offset future California state taxable
income. These carryforwards expire in various amounts through the year 2002. The
Company also has certain California tax credit carryforwards of $330,000.

NOTE 8  NET INCOME (LOSS) PER SHARE (CONTINUED)
common stock equivalents have been included in 1996 and 1997 because the effect
would be to decrease the loss per share.
 
    In February 1997, the FASB issued Statement of Financial Accounting
Standards No. 128 ("SFAS No. 128"), "Earnings Per Share", which simplifies the
standards for computing earnings per share previously found in Accounting
Principles Board Opinion No. 15 ("APB No. 15"). SFAS No. 128 replaces the
presentation of primary earnings per share with a presentation of basic earnings
per share, which excludes dilution. SFAS No. 128 also requires dual presentation
of basic and diluted earnings per share on the face of the income statement for
all entities with complex capital structures and requires a reconciliation.
Diluted earnings per share is computed similarly to fully diluted earnings per
share pursuant to APB No. 15. SFAS No. 128 must be adopted for financial
statements issued for periods ending after December 15, 1997, including interim
periods; earlier application is not permitted. SFAS No. 128 requires restatement
of all prior period earnings per share presented. The Company does not
anticipate that SFAS No. 128 will have a material impact on its earnings per
share calculation.

the Company's product in the course of employment with American Airlines from
the period May 1981 through July 1991. The plaintiff alleges damages in the
amount of $1 million and seeks punitive damages of $10 million. The Company
believes that the claim is without merit and has tendered defense of this action
to its insurance carriers. In the opinion of management, the outcome of this
litigation will not have a material adverse effect on the Company's financial
position or its results of operations.

NOTE 12  ACQUISITION OF OLD AMATI
 
    On November 28, 1995, the Company acquired all of the outstanding shares of
Amati Communications Corporation ("Old Amati") for approximately $29.5 million.
The purchase price consisted of the issuance of 2.6 million shares of the
Company's Common Stock in exchange for all shares of Old Amati common stock, 1.5
million shares of the Company's Common Stock in exchange for all shares of Old
Amati Series A preferred stock, Warrants for the purchase of up to 1.1 million
shares of the Company's Common Stock in exchange for all Old Amati warrants, and
options to purchase up to 1.6 million shares of the Company's Common Stock in
exchange for all options to purchase Old Amati common stock. The purchase price
also includes registration and other acquisition costs of $0.8 million, total
cash advances to Old Amati prior to the merger of $5.6 million and is net of the
estimated proceeds from the assumed exercise of Old Amati options and warrants
of $3.3 million.
 
    The transaction was accounted for using the purchase method of accounting.
The Company allocated the purchase price to the net assets based upon their
estimated fair values. The fair values of tangible assets acquired and
liabilities assumed were $1.2 million and $3.2 million, respectively. The
balance of the purchase price, $31.6 million, was charged to earnings to
write-off in-process research and development that had not reached 
technological feasibility and had no alternative future uses.

                           AMATI COMMUNICATIONS CORPORATION
                 NOTES TO CONSOLIDATED CONDENSED FINANCIAL STATEMENTS
                                   NOVEMBER 1, 1997
                                           
NOTE A - BASIS OF PRESENTATION

The accompanying unaudited consolidated condensed financial statements have been
prepared in accordance with the rules and regulations of the Securities and
Exchange Commission and do not include all of the information and footnotes
required by generally accepted accounting principles for complete financial
statements.  In the opinion of management, all adjustments (consisting of normal
recurring entries) considered necessary for a fair presentation have been
included.  For further information, refer to the financial statements and
footnotes included in the Company's Annual Report on Form 10-K for the year
ended August 2, 1997.  The results for the period are not necessarily indicative
of results for the full fiscal year.  

NOTE B - NET LOSS PER SHARE

Net loss per share is based on the weighted average number of shares outstanding
of common stock. No common stock equivalents have been included in fiscal years
1998 and 1997 because the effect would decrease the loss per share.

In February 1997, the FASB issued SFAS No. 128, Earnings Per Share, which 
simplifies the standards for computing earnings per share previously found in 
Accounting Principles Board Opinion ("APB") No. 15.  SFAS No. 128 replaces 
the presentation of primary earnings per share with a presentation of basic 
earnings per share, which excludes dilution.  SFAS No. 128 also requires dual 
presentation of basic and diluted earnings per share on the face of the 
income statement for all entities with complex capital structures and 
requires reconciliation.  Diluted earnings per share are computed similarly 
to fully diluted earnings per share pursuant to APBO No. 15.  SFAS No. 128 
must be adopted for financial statements issued for periods ending after 
December 15, 1997, including interim periods, earlier application is not 
permitted.  SFAS No. 128 requires restatement of all prior period earnings 
per share presented.  The Company does not anticipate that SFAS No. 128 will 
have a material impact on its earnings per share calculation.

NOTE C - INVENTORIES

Inventories are stated at the lower of cost (first-in, first-out) or market and
are comprised of the following:

                 NOTES TO CONSOLIDATED CONDENSED FINANCIAL STATEMENTS
                                   NOVEMBER 1, 1997
                                           
NOTE D - PROPOSED MERGER 

On September 30, 1997, the Company and Westell Technologies, Inc. entered 
into a proposed merger wherein Amati would have become a wholly owned 
subsidiary of Westell Technologies, Inc.

Holders of outstanding Amati Common Stock were to receive in exchange for 
each share, 0.9 shares of Westell Class A Common Stock.  Under the provisions 
of a Loan and Security Agreement dated September 30, 1997, Westell 
Technologies, Inc. could extend financing to the Company of up to $5,000,000 
secured by a promissory note due on or before September 30, 1999 with 
interest payable at the following rates: prime plus 2% for the first $1 
million and prime plus 21/2% for all borrowings in excess of $1 million.  As 
of November 1, 1997, $3,050,000 was outstanding under the Westell Loan, 
subsequently increased to $3,550,000.

Following the end of the current fiscal quarter, the Company terminated the 
agreement with Westell Technologies, Inc. paying a $14.8 million fee in 
connection with such termination.  On November 19, 1997 the Company entered 
into an Agreement and Plan of Merger with Texas Instruments, Incorporated 
("TI") providing for an all-cash tender offer for all outstanding shares of 
the Company's Common Stock at $20 per share to commence on November 25, 1997 
and ending on December 23, 1997, unless extended.  Following completion of 
the tender offer, and upon consummation of a merger with a wholly owned 
subsidiary of TI, the Company will become a wholly owned subsidiary of TI. 

Under the provisions of a Loan and Security Agreement dated November 19, 1997,
Texas Instruments agreed to grant a term loan in the amount of $14,774,000 and a
revolving loan in the amount of $5,000,000 to the Company secured by a
promissory note due September 30, 1999 with interest at the rate of prime plus
2%.  As of December 5, 1997, $18,763,000 was outstanding under the TI loan.
Proceeds from these borrowings were used to repay in full all amounts owing to
Westell under the Loan and Security Agreement dated September 30, 1997, all
amounts owing to the Silicon Valley Bank under its revolving line of credit
agreement, and to pay a termination fee to Westell Technologies, Inc.

TEXAS INSTRUMENTS INCORPORATED

NOTES TO UNAUDITED PRO FORMA COMBINED STATEMENT OF OPERATIONS


BASIS OF PRESENTATION

The accompanying unaudited pro forma combined statement of operations for the
year ended December 31, 1997 gives effect to the acquisition of Amati 
Communications Corporation (Amati) by the Registrant as if the acquisition 
had occurred on January 1, 1997.

The pro forma information is based on the audited consolidated statement of 
operations of the Registrant for the year ended December 31, 1997, and the 
unaudited consolidated statement of operations of Amati for the year ended 
November 1, 1997.

This pro forma combined statement of operations has been prepared by 
management and may not be indicative of the results of operations that 
actually would have occurred if the combination had been in effect on the 
dates indicated or which may be obtained in the future.

This pro forma statement should be read in conjunction with the audited 
financial statements and related notes of the Registrant as of and for the 
year ended December 31, 1997 and the audited financial statements and related 
notes of Amati included herein.

(a) A pro forma combined balance sheet is not presented herein because the 
assets and liabilities of Amati are reflected in the Registrant's consolidated 
balance sheet as of December 31, 1997, included in its Form 10-K filed 
February 23, 1998.

(b) To reflect the acquisition of Amati by the Registrant, the acquired 
intangibles were estimated as follows (in millions of dollars):

Purchase price                                                $     468
     Estimated acquisition costs                                          48
                                                                      ------
                                                                         516
     Less: Assets acquired                                                13
           Acquired in-process R&D immediately expensed
              in the period of acquisition                               461
                                                                      ------
     Acquired intangibles                                          $      42

The amortization of the acquired intangibles of $42 million and the related 
deferred income tax effect resulting from the acquisition of Amati over the 
weighted average estimated useful life of 9 years is included as a pro forma 
adjustment.


(c) To eliminate the acquired in-process R&D expense of $461 million.

(d) Because Amati's year-end of August 2, 1997 was not within 93 days of the
Registrant's December 31, 1997 year-end, Amati's operating results for the 
three months ended November 2, 1996 were excluded from its audited 
consolidated statement of operations for the year ended August 2, 1997, and 
its audited operating results for the three months ended November 1, 1997 
were included, resulting in an unaudited presentation of operating results 
for the year ended November 1, 1997.


                                                           Exhibit 99.2

      Texas Instruments Closes Acquisition of Amati Communications Corporation

     Dallas (February 27, 1998) - Texas Instruments Incorporated (NYSE: TXN) 
today completed its previously announced acquisition of Amati Communications 
Corporation after a special meeting of Amati stockholders.  The company was 
merged with TI's DSL Acquisition Corporation and is now a wholly-owned 
subsidiary of Texas Instruments.  TI previously acquired 77% of Amati's 
outstanding shares through a tender offer consummated on December 24, 1997.  
All outstanding shares not held by TI were converted in the merger into the 
right to receive $20.00 per share in cash.

     This acquisition strengthens TI's position for providing digital signal 
processing solutions for high-speed Internet connectivity and quality video 
services.  Amati is a world leader in digital modem technology, also known as 
Digital Subscriber Line (xDSL), which lets ordinary phone lines transmit data 
more than 100 times faster than today's 56K analog voiceband modems.  Using 
TI's digital signal processing technology, next generation modems will 
provide users with faster, more reliable access to the Internet along with 
the ability to use a single phone for simultaneous functions.  

Amati employees, along with TI employees currently focused on the modem 
market, will combine to form the Datacom Business Unit of TI's Semiconductor 
Group.
