With its excellent off isolation, the MAX4565 is ideal for
use in high-frequency video multiplexers. Figure 2
shows such an application for switching any one of four
video inputs to a single output. The same circuit may
be used as a demultiplexer by simply reversing the sig-
nal direction.

Stray capacitance of traces and the output capacitance
of switches placed in parallel reduces bandwidth, so the
outputs of no more than four individual switches should
be placed in parallel to maintain a high bandwidth. If
more than four mux channels are needed, the 4-channel
circuit should be duplicated and cascaded.
ALL GND_ PINS ARE CONNECTED TO GROUND PLANE (OV).
V- IS CONNECTED TO GND (OV) FOR SINGLE-SUPPLY OPERATION.
