18. Data sheet status
Please consult the most recently issued data sheet before initiating or completing a design.
The product status of the device(s) described in this data sheet may have changed since this data sheet was published. The latest information is available on the Internet at
For data sheets describing multiple type numbers, the highest-level product status determines the data sheet status.
19. Definitions
Short-form specification — The data in a short-form specification is
extracted from a full data sheet with the same type number and title. For
detailed information see the relevant data sheet or data handbook.
Limiting values definition — Limiting values given are in accordance with
the Absolute Maximum Rating System (IEC 60134). Stress above one or
more of the limiting values may cause permanent damage to the device.
These are stress ratings only and operation of the device at these or at any
other conditions above those given in the Characteristics sections of the
specification is not implied. Exposure to limiting values for extended periods
may affect device reliability.
Application information — Applications that are described herein for any
of these products are for illustrative purposes only. Philips Semiconductors
make no representation or warranty that such applications will be suitable for
the specified use without further testing or modification.
20. Disclaimers
Life support — These products are not designed for use in life support
