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 specication is not implied. Exposure to absolute maximum rating conditions for
extended periods may affect device reliability.
