Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause permanent or latent 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 this device specification. Exposure to absolute maximum rat-
ings for extended periods can adversely affect device reliability.
