(1) All voltages are with respect to V_SS.
(2) Maximum current drain per pin is for one pin at a time, limited by an external resistor.
Note:
This device contains circuitry designed to protect against damage due to high
electrostatic voltages or electric fields. However, it is recommended that normal
precautions be taken to avoid the application of any voltages higher than those given in
the maximum ratings table to this high impedance circuit. For maximum reliability all
unused inputs should be tied to either V_SS or V_DD.
