(1) All voltages are with respect to VSS.
(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 VSS or VDD.
