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-
cuit. For proper operation, V
in
and
V
out
should be constrained to the
range GND v (V
in
or V
out
) v 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.
