NOTE : Power Dissipation Capability will be dependent upon package characteristics and use environment. See enclosed thermal impedance data.
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 operating sections of this specification is not
implied. Exposure to absolute maximum rating conditions for extended periods may affect reliability.
