Abstract
A semiconductor device for driving a load of an object includes a differential circuit receiving an input signal and outputting differential output signals, first to fourth output circuits receiving the differential output signals, and a control circuit configured to respectively connect or disconnect the differential circuit to each of the first to fourth output circuits. The first output circuit is connected between high-level and mid-level power supply terminals and outputs a first output signal to the differential circuit, the second output circuit is connected between the high-level and mid-level power supply terminals, and outputs a second output signal to the load, a third output circuit is connected between mid-level and low-level power supply terminals, and outputs a third output signal to the differential circuit, and a fourth output circuit is connected between the mid-level low-level power supply terminals, and outputs a fourth output signal to the load.
