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. Expo sure to absolute maximum ratings for extended periods may effect device reliability.
