Abstract
A multiplexer capable of selecting and outputting only one signal from among a plurality of input signals, based on control signals. The multiplexer includes a constant current supplying section for supplying a circuit operating power and a signal input/output section for selecting and outputting only one signal from among a plurality of input signals based on control signals. The multiplexer also includes an inverter for receiving control signals and a selection signal supplying section for supplying selecting signals in accordance with the logic signals of the NOR logic section. According to the present invention, the number of input terminals is reduced, and every possible control signal combination is utilized, thereby preventing errors which normally occur when invalid control signal combinations are entered.
