Abstract
A pass transistor type selector circuit comprises a control signal supplying circuit for supplying a pair of control signals of opposite phases to the respective gate electrodes of a pair of nMOS transistors of a selecting circuit. The control signal supplying circuit includes a control signal interrupting means which operates in synchronism with a clock signal so as to selectively interrupt the supply of the control signals to the signal selecting circuit while the clock signal is low level. The control signal interrupting means is provided with a discharging means for discharging high-level one of the gate electrodes of the nMOS transistors of the signal selecting circuit while the clock signal is low level. The discharging means comprises two nMOS transistors, each connected between the respective gate electrodes of the nMOS transistors of the signal selecting circuit and a grounding terminal.
