-- IMPORTANT NOTICE --
-- --
-- Texas Instruments (TI) reserves the right to make changes to its --
-- products or to discontinue any semiconductor product or service without --
-- notice, and advises its customers to obtain the latest version of --
-- relevant information to verify, before placing orders, that the --
-- information being relied on is current. --
-- --
-- TI warrants performance of its semiconductor products and related --
-- software to the specifications applicable at the time of sale in --
-- accordance with TI's standard warranty. Testing and other quality --
-- control techniques are utilized to the extent TI deems necessary to --
-- support this warranty. Specific testing of all parameters of each --
-- device is not necessarily performed, except those mandated by --
-- government requirements. --
-- --
-- Certain applications using semiconductor products may involve potential --
-- risks of death, personal injury, or severe property or environmental --
-- damage ("Critical Applications"). --
-- --
-- TI SEMICONDUCTOR PRODUCTS ARE NOT DESIGNED, INTENDED, AUTHORIZED, OR --
-- WARRANTED TO BE SUITABLE FOR USE IN LIFE-SUPPORT APPLICATIONS, DEVICES --
-- OR SYSTEMS OR OTHER CRITICAL APPLICATIONS. --
-- --
-- Inclusion of TI products in such applications is understood to be fully --
-- at the risk of the customer. Use of TI products in such applications --
-- requires the written approval of an appropriate TI officer. Questions --
-- concerning potential risk applications should be directed to TI through --
-- a local SC sales office. --
-- --
-- In order to minimize risks associated with the customer's applications, --
-- adequate design and operating safeguards should be provided by the --
-- customer to minimize inherent or procedural hazards. --
-- --
-- TI assumes no liability for applications assistance, customer product --
-- design, software performance, or infringement of patents or services --
-- described herein. Nor does TI warrant or represent that any license, --
-- either express or implied, is granted under any patent right, copyright, --
-- mask work right, or other intellectual property right of TI covering or --
-- relating to any combination, machine, or process in which such --
-- semiconductor products or services might be or are used. --
