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