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
voltage 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
voltage level (either V
SS
or V
DD
).
Notes:

Inputs have pull-up/pull-down resistors that effect input current.
The VCMR is the difference from the most positive side of the differential input signal. Normal operation is obtained when the
“
High
”
input is within the VCMR
range and the input lies within the VPP specification. Driving series or parallel terminated 50
(or 50
to VDD/2) transmission lines.
