Abstract
A first circuit receives input signals of the first electric potential system which uses a first high potential and a first low potential as the power supply electric potential, and outputs a first signal which is a signal of the first electric potential system, a second circuit which generates output signals according to the input signal of the second electric potential system which uses as the power supply electric potential a second high potential of the first electric potential system, wherein the second circuit includes an initial stage inverter that receives the second signals and outputs third signals, and an initial stage switch that switches between connecting and disconnecting the initial stage inverter and a power supply that supplies the second high potential or a power supply that supplies the second low potential based on the first signals, and generates the output signals based on the third signals.
