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 operational sections of the data sheet. Exposure
to Absolute Maximum Ratings for extended periods can aversely affect device reliability.
