*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.
