the thermal resistance of the package

* Notice

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 conditions

above those indicated in the operational sections of this specification is

not implied. Exposure to absolute maximum rating conditions may affect

device reliability.
