Absolute Maximum Ratings are stress ratings. Stresses

in excess of these ratings can cause permanent damage

to the device. 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.
