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.
