Notes:
1. Single Power Supply: The voltage on any input or I/O pin cannot exceed the power pin during power-up.
2. These are absolute values with respect to device ground. All overshoots due to system or tester noise are included.
3. Not more than one output should be tested at a time. Duration of the short circuit should not exceed 1 second. VOUT = 0.5V has been chosen to avoid test problems
caused by tester ground degradation.
4. Tested initially and after any design or process changes that may affect these parameters.
