However, precautions must be taken to avoid applications of any voltage higher than maximum rated voltages to this high−impedance cir- cuit. For proper operation, Vin and Vout should be constrained to the range GND v (Vin or Vout) v 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. |
