Right to make changes — NXP Semiconductors reserves the right to make 
changes to information published in this document, including without 
limitation specifications and product descriptions, at any time and without 
notice. This document supersedes and replaces all information supplied prior 
to the publication hereof.
Suitability for use — NXP Semiconductors products are not designed, 
authorized or warranted to be suitable for use in life support, life-critical or 
safety-critical systems or equipment, nor in applications where failure or 
malfunction of an NXP Semiconductors product can reasonably be expected 
to result in personal injury, death or severe property or environmental 
damage. NXP Semiconductors accepts no liability for inclusion and/or use of 
NXP Semiconductors products in such equipment or applications and 
therefore such inclusion and/or use is at the customer’s own risk.
Applications — 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 to any default, 
damage, costs or problem which is based on any weakness or default in the 
customer’s applications or products, or the application or use by customer’s 
third party customer(s). Customer is responsible for doing all necessary 
testing for the customer’s applications and products using NXP 
Semiconductors products in order to avoid a default of the applications and 
the products or of the application or use by customer’s third party 
customer(s). NXP does not accept any liability in this respect.
Limiting values — Stress above one or more limiting values (as defined in 
the Absolute Maximum Ratings System of IEC 60134) will cause permanent 
damage to the device. Limiting values are stress ratings only and (proper) 
operation of the device at these or any other conditions above those given in 
the Recommended operating conditions section (if present) or the 
Characteristics sections of this document is not warranted. Constant or 
repeated exposure to limiting values will permanently and irreversibly affect 
the quality and reliability of the device.
