Note: 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 output

must be left open.
