Note: This device contains protection circuitry to guard against damage due to high static voltage or electric fields.

However, precautions must be taken to avoid applications of any voltage higher than maximum rated voltage 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.
