Abstract:
1. A selector circuit comprising: a plurality of first selectors, each of the plurality of first selectors being configured to select one of a plurality of input signals on the basis of a first selection control signal and to output a first output signal corresponding to the selected input signal; and a second selector configured to select one of the first output signals outputted from the plurality of first selectors on the basis of a second selection control signal and to output a second output signal corresponding to the selected first output signal, wherein each of the plurality of first selectors includes: a first node capable of being charged and discharged, a charger configured to be provided between a first voltage source and the first node and to charge the first node by electrically connecting the first node to the first voltage in a first period, the first period being defined by a timing control signal, and a discharge controller configured to be provided between the first node and a second voltage source having a potential lower than the first voltage source and to control, on the basis of the first selection control signal, the plurality of input signals and the second selection control signal, whether to discharge the charged first node by electrically connecting the first node to the second voltage source in a second period, the second period following the first period and being defined by the timing control signal an output circuit configured to output the first output signal having a potential according to a potential of the first node.
