Patent ID: 10720576

Abstract:
A semiconductor device includes: a first switch that uses a first selection signal and a second selection signal to select one of a first voltage and a third voltage or a second voltage and a fourth voltage from the first voltage, the second voltage lower than the first voltage, the third voltage lower than the first voltage, and the fourth voltage lower than the third voltage; a second switch that selects one of a first input signal or a second input signal from the first input signal being the first voltage or the third voltage and the second input signal being the second voltage or the fourth voltage; a third switch that outputs the third voltage in a case where the first voltage and the third voltage are selected by the first switch and the first input signal, which is the first voltage, is selected by the second switch, outputs the first voltage in a case where the first voltage and the third voltage are selected by the first switch and the first input signal, which is the third voltage, is selected by the second switch, outputs the second voltage in a case where the second voltage and the fourth voltage are selected by the first switch and the second input signal, which is the second voltage, is selected by the second switch, and outputs the fourth voltage in a case where the second voltage and the fourth voltage are selected by the first switch and the second input signal, which is the fourth voltage, is selected by the second switch; a fourth switch that outputs the first voltage in a case where the third voltage is output from the third switch, outputs the third voltage in a case where the first voltage is output from the third switch, outputs the fourth voltage in a case where the second voltage is output from the third switch, and outputs the second voltage in a case where the fourth voltage is output from the third switch; and a control circuit that controls the first switch, the second switch, the third switch and the fourth switch.
