Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress

ratings only. Functional operation above the Recommended Operating Conditions is not implied.

Extended exposure to stresses above the Recommended Operating Conditions may affect device

reliability.

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 cir-

Unused inputs must always be

tied to an appropriate logic voltage

Unused outputs must be left open.
