Abstract

A multipurpose switching circuit of the balanced type constituting a pair of switching paths each formed by first and second transistors connected in series and supplied with an input signal and a switching signal, respectively, and a novel semiconductor device of the three-terminal type with first and third terminals connected to both of the pair of switching paths, respectively, and a second terminal connected to an output terminal of the circuit. The respective second transistors of both the paths cause the switching operation to alternate in accordance with the switching signal, and both the input signals supplied to the respective first transistors of the pair of switching paths are alternately switched to the output terminal through the novel semiconductor device in response to the switching operation of the first transistors. The novel semiconductor device has a semiconductor body similar to an ordinary transistor and acts as a bidirectionally conductive element with superior symmetrical characteristics.
