ABSTRACT:
A multiplexer having a plurality of semiconductor solid state input switches arranged to be connected to respective input signal sources and arranged in groups of input switches with a plurality of the switches in each group, a plurality of selectable leakage current shunting circuits with each circuit being connected by a leakage current control switch to a respective one of the groups of the switches to provide a shunt path for leakage currents through the switches in a corresponding group and a switch control for selectively operating the solid-state switches to connect a selected one of the input signal sources in a selected one of the groups of sources to an output of the multiplexer and the leakage current switches in the non-selected groups to connect each of the solid-state input switches in the non-selected groups to the respective ones of the current shunting circuits.
