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