3.3V, 180MHz, Multi-Output Zero Delay Buffer
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).

Note 1: The voltage on any input or I/O pin cannot exceed the power pin during power-up. Power supply sequencing is NOT
required.
Note 2: Inputs have pull-up, pull-down resistors that affect input current.
Note 3: 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.
Note 4: Driving series or parallel terminated 50Ω (or 50Ω to VDD/2) transmission lines. Output buffers are dual staged to control
drive strength in order to reduce over/under shoot.
