* Maximum Ratings are those values beyond which damage to the device may occur.

This device contains circuitry to protect the

inputs against damage due to high static volt-

ages or electric fields; however, it is advised that

normal precautions be taken to avoid applica-

tions of any voltage higher than maximum rated

voltages to this high–impedance circuit. For

proper operation it is recommended that Vin and

Vout be constrained to the range VSS ≤ (Vin or

Vout) ≤ VDD.

Unused inputs must always be tied to an

appropriate logic voltage level (e.g., either VSS

or VDD).
