This device contains circuitry to protect the inputs against damage due to high static voltages or
electric fields. However, it is advised that normal precautions should be taken to avoid application
of any voltage higher than the maximum rated voltages to this high impedance circuit. For proper
operation it is recommended that Vin and Vout be constrained to the range V_SS≤(V_in or V_out)≤V_DD.
Reliability of operation is enhanced if unused inputs are connected to an appropriate logic voltage
level (e.g. either V_SS or V_DD).
