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 voltage higher than the maximum rated voltages to this circuit. For proper operation, Vin and Vout should be constrained to the range:

V_SS<(Vin or V out)<V _DD

Unused inputs must always be tied to an appropriate
logic voltage level (either VSS or VDD).
