ABSOLUTE MAXIMUM CONTINUOUS RATINGS are those values beyond which damage to the device may occur.
Exposure to these conditions or conditions beyond those indicated may adversely affect device reliability.
Correct functional operation while operating in the absolute maximum rated conditions is not implied.
