Stresses 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.
