8.0 ELECTRICAL CHARACTERISTICS
8.1. 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
remainder of Section 7.0. Exposure to absolute maximum ratings for extended periods can adversely affect device reliability.
