Notes:
1. Single Power Supply: The voltage on any input or I/O pin cannot exceed the power pin during power-up.
2. T
A
is the “instant on” case temperature.
3. Tested one output at a time, output shorted for less than one second, less than 10% duty cycle.
4. Input currents are always positive at all voltages above V
