DEFINITIONS
Product specification ⎯ The information and data
provided in a Product data sheet shall define the
specification of the product as agreed between NXP
Semiconductors and its customer, unless NXP
Semiconductors and customer have explicitly agreed
otherwise in writing. In no event however, shall an
agreement be valid in which the NXP Semiconductors
product is deemed to offer functions and qualities beyond
those described in the Product data sheet.

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.

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.

Legal information
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.
Terms and conditions of commercial sale ⎯ NXP
Semiconductors products are sold subject to the general
terms and conditions of commercial sale, as published at
http://www.nxp.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. NXP
Semiconductors hereby expressly objects to applying the
customer’s general terms and conditions with regard to the
purchase of NXP Semiconductors products by customer.

implication of any license under any copyrights, patents or
other industrial or intellectual property rights.
Export control ⎯ This document as well as the item(s)
described herein may be subject to export control
regulations. Export might require a prior authorization from
national authorities.
Quick reference data ⎯ The Quick reference data is an
extract of the product data given in the Limiting values and
Characteristics sections of this document, and as such is
not complete, exhaustive or legally binding.
Non-automotive qualified products ⎯ Unless this data
sheet expressly states that this specific NXP
Semiconductors product is automotive qualified, the
product is not suitable for automotive use. It is neither
qualified nor tested in accordance with automotive testing
or application requirements. NXP Semiconductors accepts

and use in automotive applications to automotive
specifications and standards, customer (a) shall use the
product without NXP Semiconductors’ warranty of the
product for such automotive applications, use and
specifications, and (b) whenever customer uses the
product for automotive applications beyond NXP
Semiconductors’ specifications such use shall be solely at
customer’s own risk, and (c) customer fully indemnifies
