Note:

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 absolute 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.
