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 opera-
tion 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 maximum
rating conditions for extended periods can adversely affect device reliability.
