 Applications that are described herein for 

any of these products are for illustrative purposes only. 
NXP Semiconductors makes no representation or 
warranty that such applications will be suitable for the 
specified use without further testing or modification. 

Customers are responsible for the design and operation of 
their applications and products using NXP 
Semiconductors products, and NXP Semiconductors 
accepts no liability for any assistance with applications or 
customer product design. It is customer’s sole 
responsibility to determine whether the NXP 
Semiconductors product is suitable and fit for the 
customer’s applications and products planned, as well as 
for the planned application and use of customer’s third 
party customer(s). Customers should provide appropriate 
design and operating safeguards to minimize the risks 
associated with their applications and products. 

NXP Semiconductors does not accept any liability related
