*NOTICE:
Stresses at or above those listed under “ Abso-
lute 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.
Power dissipation value is based on the maxi-
mum allowable die temperature and the thermal
resistance of the package.
