Crosspoints and Multiplexers

Active crosspoint switches and active analog multiplexers have high-impedance inputs and buffered outputs. The resulting benefit is that the input signal source is isolated from the output load.

In comparison, passive analog multiplexers connect the input to the output through a low-resistance analog switch, and the input signal source must be able to drive the output load.

See a table of Maxim's passive Analog Multiplexers.

For digital video applications, Maxim also offers switches and fanout devices for DVI™/HDMI™/DisplayPort™ interfaces.
