WARNING AND DISCLAIMER 

Replace components on the Evaluation Board only with those parts shown on the parts list (or Bill of Materials) in the Users’ Guide. Contact an 
authorized Fairchild representative with any questions. 

This board is intended to be used by certified professionals, in a lab environment, following proper safety procedures. Use at your own risk. The 
Evaluation board (or kit) is for demonstration purposes only and neither the Board nor this User’s Guide constitute a sales contract or create any kind 
of warranty, whether express or implied, as to the applications or products involved. Fairchild warrantees that its products meet Fairchild’s published 
specifications, but does not guarantee that its products work in any specific application. Fairchild reserves the right to make changes without notice to 
any products described herein to improve reliability, function, or design. Either the applicable sales contract signed by Fairchild and Buyer or, if no 
contract exists, Fairchild’s standard Terms and Conditions on the back of Fairchild invoices, govern the terms of sale of the products described herein.  

DISCLAIMER  

FAIRCHILD SEMICONDUCTOR RESERVES THE RIGHT TO MAKE CHANGES WITHOUT FURTHER NOTICE TO ANY PRODUCTS HEREIN TO 
IMPROVE RELIABILITY, FUNCTION, OR DESIGN. FAIRCHILD DOES NOT ASSUME ANY LIABILITY ARISING OUT OF THE APPLICATION OR 
USE OF ANY PRODUCT OR CIRCUIT DESCRIBED HEREIN; NEITHER DOES IT CONVEY ANY LICENSE UNDER ITS PATENT RIGHTS, NOR

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 THE PRESIDENT 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, or (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 significant injury to the user. 

2.  A critical component is 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, 
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. 

EXPORT COMPLIANCE STATEMENT 

These commodities, technology, or software were exported from the United States in accordance with the Export Administration Regulations for the 
ultimate destination listed on the commercial invoice. Diversion contrary to U.S. law is prohibited. 
U.S. origin products and products made with U.S. origin technology are subject to U.S Re-export laws. In the event of re-export, the user will be 
responsible to ensure the appropriate U.S. export regulations are followed.
