General
This device contains circuitry protecting against damage due to high static voltage or
electrical fields; however, it is advised that normal precautions be taken to avoid
application of any voltages higher than maximum-rated voltages to this high-impedance
circuit. Reliability of operation is enhanced if unused inputs are tied to an appropriate
logic voltage level (for instance, either VSS or VDD) or the programmable pullup resistor
associated with the pin is enabled.
