LIFE SUPPORT POLICY
FAIRCHILD’S PRODUCTS ARE NOT AUTHORIZED FOR USE AS CRITICAL COMPONENTS IN LIF E SUPPORT DEVICES OR SYSTEMS WITHOUT THE
EXPRESS WRITTEN APPROVAL OF FAIRCHILD SEMICONDUCTOR CORPORATION.
As used herein:
1. Life support devices or systems are devices or systems which, (a)
are intended for surgical implant into the body or (b) support or
sustain life, and (c) whose failure to perform when properly used in
accordance with instructions for use provided in the labeling, can be
reasonably expected to result in a significant injury of the user.
2. A critical component in any component of a life support, device, or
system whose failure to perform can be reasonably expected to
cause the failure of the life support device or system, or to affect its
safety or effectiveness.

Fairchild Semico nductor Cor poration's An ti-Counter feiting Poli cy. Fairchi ld's An ti-Counter feiting Policy is also state d on ou r external website, w ww.fair childsemi.com ,
under Sales Support.
Counterfeiting of sem iconductor parts is a grow ing problem in the industry. Al l manu facturers of semicon ductor pro ducts are e xp eriencing counter feiting of thei r
parts. Customers w ho inadverten tly purch ase coun terfeit p arts experien ce many problem s such as loss of brand repu tation, substan dard performan ce, failed
applications, and incr eased cost o f productio n and man ufacturing delay s. Fairchild is taking strong mea sures to pro tect oursel v es and our custome rs from the
proliferatio n of counterfeit parts. F airchild strongly encourage s customers to purchase Fairchild parts either dire ctly from Fairc hild or from Autho rized Fairchil d
Distributors who are listed by country on our web page cited above. Products customers buy either from Fairchild directly or from Authorized Fairchild Distrib utors
are genuine par ts, hav e full tr aceability , meet Fairchild' s quality standards for handling and storage and pr ovide a ccess to Fa irchild's full range of up-to-date technical
