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 circuit. For proper operation, V
IN
and V
OUT
should be constrained to the range GND
≤
(V
IN
or
V
OUT
)
≤
V
CC
.
Unused inputs must always be tied to an appropriate logic voltage level (e.g., either GND or V
CC
). Unused
outputs must be left open.
