Abstract
According to one embodiment, a semiconductor switch includes a power supply section, a driver, and a switch section. The power supply section is configured to generate a first potential higher than a positive power supply potential, and a negative second potential. The driver is connected to the power supply section and configured to output a control signal. A potential of the control signal is set to the first potential at high level and set to the second potential at low level according to a terminal switching signal. The switch section is configured to receive the control signal and switch a connection between terminals. The driver has a first level shifter, a second level shifter and a first circuit. The first level shifter has a first high-side switch and a first low-side switch. The second level shifter has a second high-side switch and a second low-side switch.
