Suitability for use — Nexperia 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 a Nexperia product can reasonably be expected
to result in perso nal injury, death or severe propert y or environment al
damage. Nexperia and its suppliers accept no liability for
inclusion and/or use of Nexperia products in such equipment or
applications and ther efore such inclu sion and/or use is at the cu stomer’s own
risk.
Applications — Applications that are described herein for any of these
products are for illustrative purposes only. Nexperia 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 ope ration of their applications
and products using Nexperia products, and Nexperia
accepts no liability for any assistance with applications or customer product
design. It is customer’s sole responsibility to determine whether the Nexperia
product is suitable and fit for the customer’s applications and
products planned, as well as fo r the planned application and use of
customer’s third party customer(s). Custo mers should provide appropriate
design and operating safeguards to minimize the risks associate d with their
applications and products.
Nexperia 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 custo mer(s). Customer is responsible for doing all necessary
testing for the customer’s applications and products using Nexperia
products in order to avoid a default of the applications and
the products or of the application or use by cust omer’s third party
customer(s). Nexperia 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.
Terms and conditions of commercial sale — Nexperia
products are sold subject to the general terms and conditions of commercial
sale, as published at http://www.nexperia.com/profile/terms, unless otherwise
agreed in a valid written individua l agreement. In case an individual
