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, Vin and Vout should be constrained to the
range:
VSS < (Vin or Vout) < VDD
Unused inputs must always be tied to an appropriate logic volt-
age 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.
DC Parameters: VDD = VDDC = 3.3V ±10% or 2.5V ±5%, Over the specified temperature range
