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

ANTI-COUNTERFEITING POLICY
Fairchild Semiconductor Corporation's Anti-Counterfeiting Policy. Fairchild's Anti-Counterfeiting Policy is also stated on our external website,
www.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 delays. 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 warranties and will appropriately address any warranty issues that
may arise. Fairchild will not provide any warranty 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 buying direct or from authorized distributors.
