15 Channels Cascaded MAX455 Video Mux

Here’s a circuit for showing two MAX455s IC chip are cascaded to build a 1 of 15 video Multiplexer. This is the figure of the circuit;

This cascading is done by connecting the output of one MAX455 MUX to one input of a second MAX455 MUX. The output of the first MUX should be terminated to ground using a 75R resistor, to preserve bandwidth although the two devices are usually close to one another
