Abstract
A bus switch with level shifting may include a first terminal configured to receive and output a first power supply voltage higher than a reference voltage, a second terminal configured to receive and output a second power supply voltage higher than the first power supply voltage, an output control terminal to which a control signal for controlling a switching between an output permitted state and an output prohibited state is inputted, a first switching element provided between the first terminal and the second terminal and having a gate, a gate control circuit to which signals are inputted from the output control terminal and the second terminal, which supplies gate voltage to the gate of the first switching element, and which controls the first switching element to be conducting or to be non-conducting, and a second switching device provided between a power source of the second power supply voltage and the second terminal, and configured to switch between conducting and non-conducting in accordance with the electric potential of the second terminal.
