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 sec-

tions of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect de-

vice reliability.
