Absolute Maximum Ratings

Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are absolute stress

ratings only. Functional operation of the device is not implied at these or any other conditions in excess of those given in

the operational sections of the data sheet. Exposure to absolute maximum ratings for extended periods can adversely affect

device reliability.
