Note:
Stresses at or above those listed under “Absolute
Maximum Ratings” may cause permanent damage
to the device. This is a stress rating only and func-
tional operation of the device at these or any other
conditions above those indicated in the operational
sections of this specification is not implied. Expo-
sure to absolute maximum rating conditions may
affect device reliability.
Power dissipation value is based on the maximum
allowable die temperature and the thermal resis-
tance of the package.
