LIFE SUPPORT POLICY
FAIRCHI LD’S PRODUCTS ARE NOT AUTHORIZED F OR USE AS CRITI CAL COM PONENTS IN LI FE SUPPORT DEVICES OR SY STEMS WITHOUT THE
EXPRESS WRITTEN APPROVAL OF FAI RCHI LD SEM ICONDUCTOR CO RPORATION.
As used herein:
1. Life support devices or systems are devices or systems which, (a) are
intended for surgical im plant 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.
ANTI-COUNTERFEITING POLICY
Fairchild Semiconductor Corporation's Anti-Counterfeiting Policy. Fairchild's Anti-Counterfeiting Policy is also stated on our external website, w ww.fairchildsemi.com,
under Sales Support.
Counterfeiting of semiconductor parts is a growing problem in the industry. All manufacturers of semiconductor products are experiencing counterfeiting of their parts.
Customers who inadvertently purchase counterfeit parts experience many problems such as loss of brand reputation, substandard performance, failed applications,
and increased cost of production and manufacturing delay s. Fairchild is taking strong measures to protect ourselves and our customers from the proliferation of
counterfeit parts. Fairchild strongly encourages customers to purchase Fairchild parts either directly from Fairchild or from Authorized Fairchild Distributors who are
listed by country on our web page cited above. Products customers buy either from Fairchild directly or from Authorized Fairchild Distributors are genuine parts, have
full traceability, meet Fairchild's quality standards for handling and storage and provide access to Fairchild's full range of up-to-date technical and product information.
Fairchild and our Authorized Distributors will stand behind all w arranties and will appropriately address any warranty issues t hat may arise. Fairch ild will not p rovide
any w arranty coverage or other assistance for parts bought from Unauthorized Sources. Fairchild is committed to combat this global problem and encourage our
customers to do their part in stopping this practice by buy ing direct or from authorized distributors.
