Absolute Maximum Ratings  

Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be opera-  

ble above the recommended operating conditions and stressing the parts to these levels is not recommended. In addi-  

tion, extended exposure to stresses above the recommended operating conditions may affect device reliability. The  

absolute maximum ratings are stress ratings only. Values are at T

A

= 25°C unless otherwise noted.

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 THE RIGHTS OF OTHERS. THESE  

SPECIFICATIONS DO NOT EXPAND THE TERMS OF FAIRCHILD’S WORLDWIDE TERMS AND CONDITIONS, SPECIFICALLY THE WARRANTY THEREIN,  

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:  

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, 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  

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 oursel

v

e

s 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.
