Stresses exceeding those listed in the Maximum Ratings table may damage the device. If any of

these limits are exceeded, device functionality should not be assumed, damage may occur and

reliability may be affected.

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-

range GND

Unused inputs must always be

tied to an appropriate logic voltage

Unused outputs must be left open.
