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:
2. 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.
3. Inputs have pull-up/pull-down resistors that effect input current.
4. Driving series or parallel terminated 50Ω (or 50Ω to V
DD
/2) transmission lines.
5. Parameters are guaranteed by design and characterization. Not 100% tested in production. All parameters specified with loaded outputs.
6. Outputs driving 50Ω transmission lines.
7. 50% input duty cycle.
8. See Figure 1.
9. Part-to-Part skew at a given temperature and voltage.
