CAUTION: Stresses beyond those listed under Absolute Maximum Specifications may cause permanent damage

the device. This is a stress rating only and functional operation of the device at these or other conditions beyo

those indicated in the operational sections of this specification is not implied. Exposure to absolute maximu

specification conditions for extended periods may affect device reliability
