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 abso-
lute 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.
