* Absolute maximum continuous ratings are those values beyond which damage to the device

may occur. Exposure to these conditions or conditions beyond those indicated may

adversely affect device reliability. Functional operation under absolute−maximum−rated

conditions is not implied.

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.
