Information of third parties may be subject to additional restrictions.Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirementsconcerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or supportthat may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards thatanticipate dangerous failures, monitor failures and their consequences, lessen the likelihood of dangerous failures and take appropriateremedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use of any TI components inBuyer’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 tohelp enable customers to design and create their own end-product solutions that meet applicable functional safety standards andrequirements. Nonetheless, such components are subject to these terms.No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the partieshave 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 inmilitary/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components thathave not been so designated is solely at Buyer's risk, and Buyer is solely responsible for compliance with all legal and regulatoryrequirements in connection with such use.TI has specifically designated certain components as meeting ISO/TS16949 requirements, mainly for automotive use. In any case of use ofnon-designated products, TI will not be responsible for any failure to meet ISO/TS16949.IMPORTANT NOTICE
