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 outside of those
indicated in the operation sections of this specification is not implied. Exposure
to absolute maximum ratings for extended periods may affect device reliability.
