Absolute Maximum Ratings are stress ratings. Functional
operation of the device at these or any other conditions
beyond those indicated in the operational sections of this
data sheet is not implied. Exposure of the device to the
absolute maximum ratings for an extended period may
degrade the device and effect its reliability.
