... Data Sheet 120MHz, Low Power Video Crosspoint Switch The HA456 is the first video crosspoint switch suitable for high performance video systems. Its high level of integration significantly reduces component count, board space, and cost. The crosspoint switch contains a digitally controlled matrix of 64 fully buffered switches that connect eight video input signals to any, or all, matrix outputs ...

... Figure 2 shows a typical application of the HA456 with HFA1412 quad, gain-of-two buffers at the outputs to drive 75 loads. This application shows the HA456 digital-switch control interface set up in the 7-bit parallel mode. The HA456 uses 7 data lines and 3 control lines (WR, CE and LATCH). The input/output information is presented to the chip at A2:0 and D3 parallel printer port ...
