This device contains protection circuitry to guard against damage due to high static voltages or electric
fields. However, precautions must be taken to avoid applications of any voltage higher than maximum rated voltages
to this high-impedance circuit. For proper operation, VIN and VOUT should be constrained to the range GND≤(VIN or
VOUT)≤VCC.
Unused inputs must always be tied to an appropriate logic voltage level (e.g., either GND or VCC). Unused
outputs must be left open.
