A selector circuit includes a plurality of first selection circuits each configured to select one of plural input signals on the basis of a first selection control signal and to output a first output signal and a second selection circuit configured to select one of the first output signals on the basis of a second selection control signal. Each of the first selection circuits includes a charging circuit configured to charge a first node by electrically connecting the first node to a first voltage in a first period, and a discharge control circuit configured to control, on the basis of the first selection control signal, the input signals and the second selection control signal, whether to discharge the charged first node by electrically connecting the first node to a second voltage source having a potential lower than the first voltage source in a second period following the first period.
