Absolute maximum ratings

Stresses above those listed as “absolute maximum ratings” may cause permanent damage

to the Device. This is a stress rating only and functional operation of the Device under these

conditions is not implied. Exposure to maximum rating conditions for extended periods may

affect device reliability.
