Notice:
1. Stresses 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 conditions above those indicated in the
operational sections of this specification is not implied.
Exposure to absolute maximum rating conditions for
extended periods may affect device reliability.
2. This value is based on the maximum allowable die temperate
and the thermal resistance of the package.
