Short data sheet — A short data sheet is an extract from a full data sheet
with the same product type number(s) and title. A short data sheet is
intended for quick reference only and should not be relied upon to contain
detailed and full information. For detailed and full information see the
relevant full data sheet, which is available on request via the local Nexperia
sales office. In case of any inconsistency or conflict with the short data sheet,
the full data sheet shall prevail.
Product specification — The information and data provided in a Product
data sheet shall define the specification of the product as agreed between
Nexperia and its customer, unless Nexperia and customer have explicitly
agreed otherwise in writing. In no event however, shall an agreement be
valid in which the Nexperia product is deemed to offer functions and qualities
beyond those described in the Product data sheet.

Right to make changes — Nexperia 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.
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 operation 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 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. 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 customer(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 customer’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 individual agreement. In case an individual agreement is
concluded only the terms and conditions of the respective agreement shall
apply. Nexperia hereby expressly objects to applying the customer’s general
terms and conditions with regard to the purchase of Nexperia products by
customer.

or construed as an offer to sell products that is open for acceptance or
the grant, conveyance or implication of any license under any copyrights,
patents or other industrial or intellectual property rights.
Suitability for use in automotive applications — This Nexperia product
has been qualified for use in automotive applications. Unless otherwise
agreed in writing, the product is 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 Nexperia
product can reasonably be expected to result in personal injury, death or
severe property or environmental damage. Nexperia and its suppliers accept
no liability for inclusion and/or use of Nexperia products in such equipment or
applications and therefore such inclusion and/or use is at the customer's own
