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