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 abso-

lute 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.
