This device contains protection

circuitry to guard against damage

due to high static voltages or elec-

tric fields. However, precautions

must be taken to avoid applications

of any voltage higher than maxim-

um rated voltages to this high−im-

pedance circuit. For proper opera-

Unused inputs must always be

tied to an appropriate logic voltage

used outputs must be left open.
