Maximum Power Supply: ................................................5.5V
Maximum Input Current: ...........................................± 20 mA
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, Vin and Vout should be constrained to the
range:
VSS < (Vin or Vout) < VDD .
Unused inputs must always be tied to an appropriate logic
voltage level (either VSS or VDD).
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 50
Ω (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 50
Ω transmission lines.
7. 50% input duty cycle.
8. See Figure 1.
9. Part-to-Part skew at a given temperature and voltage.
DC Electrical Specifications: VDD = VDDC = 3.3V ±10% or 2.5V ±5%, over the specified temperature range
