Abstract
A multiplexing apparatus for outputting selected input signals utilizes input transistors coupled between input sources and diodes. A first set of switching transistors, coupled to the input transistors and the diodes, blocks the outputting of nonselected input signals by applying a predetermined voltage to the anodes of corresponding diodes. A second set of switching transistors, coupled to the input transistors and the diodes, permits the outputting of selected input signals on the emitters of output transistors coupled to the diodes, by applying current to the emitters of corresponding input transistors, and the anodes of corresponding diodes.
