* Stresses above those listed 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 specification is not implied. Exposure to absolute maximum rating conditions for extended

periods may affect device reliability (eq. hot carrier degradation).
