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 the specification is not implied. Exposure to

absolute maximum ratings for extended periods may effect device reliability.
