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.
