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)ﾣ 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.
