NOTE:

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.
