NOTE: Stresses greater than 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 speci-

fication is not implied. Exposure to absolute maximum rating conditions

for extended periods may affect reliability.

RECOmmENDED CONDITIONS

Typical deratings of the thermal resistances are given for ambient

temperature >25°.
