... Both devices offer a high-speed disable feature that allows the outputs to be put into a high impedance state. This allows the building of larger input arrays while minimizing “OFF” chan- nel output loading. The AD8074/AD8075 are offered in a 16-lead TSSOP package. Rev. B 500 MHz and +2 Triple ...

... L –2.0 Single Supply Operation The AD8074 and AD8075 may be operated from a single 10 V supply. In this configuration, the AD8075’s AGND pins must be tied near midsupply, as AGND provides the reference for the ground buffer, to which the internal gain network is terminated. Logic is referenced to DGND. The buffers are disabled in single supply operation for V > ...

... AD8074/AD8075 RGB Buffer for Second Monitor The RGB signals for PC monitors are driven through coax cables whose characteristic impedance is 75 Ω. The graphics chip will generally have current-source output drivers that should be double terminated with a 75 Ω shunt termination at each end. ...

... Triple Video Multiplexer The AD8074 and AD8075 each have an output-enable function that can be used to disable the outputs and put them in a high- impedance state. Usually, for a unity-gain device relatively easy to provide high disabled impedance, because the feedback path is from the output to a high-impedance input. However, for a non-unity-gain part, the feedback provides a resistive path to ground ...

... desired to design such a multiplexer at unity gain, the AD8074 should be used. For a triple 3:1 multiplexer, an AD8183 (triple 2:1 mux) can be combined with an AD8074 to provide this function. Layout and Grounding The AD8074 and AD8075 are extreme bandwidth, high-slew-rate devices that are designed to drive up to the highest resolution monitors and provide excellent resolution ...
