ANTI-COUNTERFEITING POLICY

Fairchild Semiconductor Corporation’s Anti-Counterfeiting Policy. Fairchild’s Anti-Counterfeiting Policy is also stated on our external website,

Counterfeiting of semiconductor parts is a growing problem in the industry. All manufactures 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

application, 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 handing 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 and

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.
