1Stresses above those listed under Absolute Maximum Ratings may cause

permanent damage to the device. This is a stress rating only; functional

operation of the device at these or any other conditions above those

indicated in the operational section of this specification is not implied.

Exposure to absolute maximum rating conditions for extended periods may

affect device reliability.
