DEFINITIONS
Data sheet status
Objective specification This data sheet contains target or goal specifications for product development.
Preliminary specification This data sheet contains preliminary data; supplementary data may be published later.
Product specification
This data sheet contains final product specifications.
Limiting values
Limiting values are given in accordance with the Absolute Maximum Rating System (IEC 134). 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
this specification is not implied. Exposure to limiting values for extended periods may affect device reliability.
Application information
Where application information is given, it is advisory and does not form part of the specification.
Ó
LIFE SUPPORT APPLICATIONS
These products are not designed for use in life support appliances, devices or systems where malfunction of these
products can be reasonably expected to result in personal injury. Philips customers using or selling these products
for use in such applications do so at their own risk and agree to fully indemnify Philips for any damages resulting
from such improper use or sale.
