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 conditions above those indicated in
the operational sections of this specification is not implied.
Exposure to absolute maximum rating conditions may affect
device reliability.
The power dissipation is based on the maximum allowable
die temperature and the thermal resistance of the package.
