Abstract:
There is provided a semiconductor device including (1) a first power source section that includes a first power source output terminal and a second power source output terminal that output voltages at mutually different voltage levels, (2) a first output section that includes a first output stage switch that is provided between the first power source output terminal and a first voltage output terminal, and a second output stage switch that is provided between the second power source output terminal and the first power source output terminal, and (3) a controller that performs ON/OFF control of the first output stage switch and the second output stage switch such that both the first output stage switch and the second output stage switch are in an OFF state over a predetermined period encompassing a point in time when a signal level of the first signal switches.
