5 IMPORTNT NOTIE FOR TI REFERENE ESIGNS Texas Instruments Incorporated ("TI") reference designs are solely intended to assist designers ( uyers ) who are developing systems that incorporate TI semiconductor products (also referred to herein as components ). uyer understands and agrees that uyer remains responsible for using its independent analysis, evaluation and judgment in designing uyer s systems and products. TI reference designs have been created using standard laboratory conditions and engineering practices. TI has not conducted any testing other than that specifically described in the published documentation for a particular reference design. TI may make corrections, enhancements, improvements and other changes to its reference designs. uyers are authorized to use TI reference designs with the TI component(s) identified in each particular reference design and to modify the reference design in the development of their end products. HOWEVER, NO OTHER LIENSE, EXPRESS OR IMPLIE, Y ESTOPPEL OR OTHERWISE TO NY OTHER TI INTELLETUL PROPERTY RIGHT, N NO LIENSE TO NY THIR PRTY TEHNOLOGY OR INTELLETUL PROPERTY RIGHT, IS GRNTE HEREIN, including but not limited to any patent right, copyright, mask work right, or other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information published by TI regarding third-party products or services does not constitute a license to use such products or services, or a warranty or endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the third party, or a license from TI under the patents or other intellectual property of TI. TI REFERENE ESIGNS RE PROVIE "S IS". TI MKES NO WRRNTIES OR REPRESENTTIONS WITH REGR TO THE REFERENE ESIGNS OR USE OF THE REFERENE ESIGNS, EXPRESS, IMPLIE OR STTUTORY, INLUING URY OR OMPLETENESS.

TI reserves the right to make corrections, enhancements, improvements and other changes to its semiconductor products and services per JES, latest issue, and to discontinue any product or service per JES, latest issue. uyers should obtain the latest relevant information before placing orders and should verify that such information is current and complete. ll semiconductor products are sold subject to TI s terms and conditions of sale supplied at the time of order acknowledgment. TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI s terms and conditions of sale of semiconductor products. Testing and other quality control techniques for TI components are used to the extent TI deems necessary to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily performed. TI assumes no liability for applications assistance or the design of uyers products. uyers are responsible for their products and applications using TI components. To minimize the risks associated with uyers products and applications, uyers should provide adequate design and operating safeguards. Reproduction of significant portions of TI information in TI data books, data sheets or reference designs is permissible only if reproduction is without alteration and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered documentation. Information of third parties may be subject to additional restrictions. uyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support that may be provided by TI. uyer represents and agrees that it has all the necessary expertise to create and implement safeguards that anticipate dangerous failures, monitor failures and their consequences, lessen the likelihood of dangerous failures and take appropriate remedial actions. uyer will fully indemnify TI and its representatives against any damages arising out of the use of any TI components in uyer s safety-critical applications. In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI s goal is to help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and requirements. Nonetheless, such components are subject to these terms. No TI components are authorized for use in F lass III (or similar life-critical medical equipment) unless authorized officers of the parties have executed an agreement specifically governing such use. Only those TI components that TI has specifically designated as military grade or enhanced plastic are designed and intended for use in military/aerospace applications or environments. uyer acknowledges and agrees that any military or aerospace use of TI components that have not been so designated is solely at uyer's risk, and uyer is solely responsible for compliance with all legal and regulatory requirements in connection with such use. TI has specifically designated certain components as meeting ISO/TS99 requirements, mainly for automotive use. In any case of use of non-designated products, TI will not be responsible for any failure to meet ISO/TS99.
