This device contains circuitry to protect the inputs against
damage due to high static voltages or electric field; however,
precautions should be taken to avoid application of any volt-
age higher than the maximum rated voltages to this circuit. For
proper operation, V
in
and V
out
should be constrained to the
range:
V
SS
< (V
in
or V
out
) < V
DD
Unused inputs must always be tied to an appropriate logic volt-
age level (either V
SS
or V
DD
).

Multiple Supplies:
The voltage on any input or I/O pin cannot exceed the power pin during power-up. Power supply sequencing is NOT required.
Inputs have pull-up/pull-down resistors that effect input current.
The V
is the difference from the most positive side of the differential input signal. Normal operation is obtained when the
“
High
”
input is within the V
CMR
range and the input lies within the V
specification.
