DOCUMENT
STATUS(1) PRODUCT
STATUS(2) DEFINITION
Objective data sheet D ev elopment This document contains data from the objective specification for product
development.
Preliminary data sheet Qualification This document contains data from the preliminary specification.
Product data sheet Production This document contains the pr oduct specification.
DEFINITIONS
Product specification The information and da ta
provided in a Product data she et shall define the
specification of the product as agreed between NXP
Semiconductors and its custo m er, unless NXP
Semiconductors and cus to mer have explicitly agreed
otherwise in writing. In no event however, shall an
agreement be valid in which th e NXP Semiconductors
product is deemed to offer functions and qualities beyond
those described in the Product data sheet.
DISCLAIMERS
Limited warranty and liability Information in this
document is believed to be accurate and reliable.
However, NXP Semiconduc tors does not give any
representations or warranties, expressed or implied, as to

removal or replacement of any products or rework
charges) whether or not such damages are based on tort
(including negligence), warranty, breach of contract or any
other legal theory.
Notwithstanding any damages that customer might incur
for any reason whatsoever, NXP Semiconductors
aggregate and cumulative liability towards customer for
the products described herein shall be limited in
accordance with the Terms and conditions of comme rcial
sale of NXP Semiconductors.

without notice. This document supersedes and replaces all
information su pplied prior to the publica t ion 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 sys tems or
equipment, nor in applications where failure or malfunction
of an NXP Semiconductors product can reasonably be
expected to res ult in personal injur y, de ath or severe
property or environmental damage. NXP Semiconductors
accepts no liability for inclusion and/or use of NXP
Semiconductor s pr od ucts in such equipment or
application s and therefore such inclusion and /o r 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 pro du ct is su itable and fit for the
customer’s applications and products planned, as well as
for the planned application and use of custo m er’s third
party customer(s). Customers should provide appropriate
design and opera ting safeguards to minimize the risks
associated with their ap plications and pr oducts.

NXP Semiconductors does not accept any liability related
to any default, damage, cost s or problem which is based
on any weakness or default in the customer’s applications
or products, or the applic ation 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 Semic on ductors products in order to
avoid a default of the app lications and the products or of
the application or use by cust omer’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 ra tings only and
(proper) operat ion of the device at these or any other
conditions above those given in the Recommende d
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 qua l ity and
reliability of the device.

agreed in a valid written individual agreeme nt. In case an
individual agreeme nt is co nc luded only the terms and
conditions of the resp ective agreement shall app ly. NXP
Semiconductors hereby expressly objects to applying the
customer’s general terms and conditions with regard to the
purchase of NXP Semicon ductors produc ts by customer.
No offer to sell or license Nothing in this document
may be interpreted or construed as an offer to sell products
that is open for accepta nc e or the grant, conveyance or
