Multiple Supplies: The voltage on any input or I/O pin cannot exceed the power pin during power-up. Power supply sequencing is NOT required.
Inputs have pull-up/pull-down resistors that effect input current.

This device contains circuitry to protect the inputs against
damage due to high static voltages or electric field; however,
precautions should be taken to avoid application of any volt-
age higher than the maximum rated voltages to this circuit. For
proper operation, V
