WARNING
Stresses in excess of the absolute maximum limits 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 normal Min & Max values stated. Exposure to absolute maximum ratings for extended periods can adversely affect device reliability.
