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.
