Stresses at or above those listed under “Absolute
Maximum Ratings” may cause permanent damage to
the device. This is a stress rating only and functional
operation of the device at these or any other condi-
tions above those indicated in the operational
sections of this specification is not implied. Exposure
to absolute maximum rating conditions may affect
device reliability.
Power Dissipation value is based on the maximum
allowable die temperature and the thermal resistance
of the package.
