Note:
If Ics are stressed beyond those listed above “absolute maximum ratings”, they may be permanently destroyed. These are stress ratings only, and
functional operation of the device at these or any other condition beyond those indicated under “recommended operating conditions” is not implied.
Exposure to absolute maximum rated conditions for extended periods may affect device reliability.
