ABSTRACT:
A voltage switching circuit selects a voltage from among a plurality of input voltages in response to a selection signal and outputs the selected voltage from an output terminal. The voltage switching circuit includes a first PMOS transistor that outputs a power supply voltage for operating a logic circuit of an output terminal. A second PMOS transistor outputs a first voltage higher than the power supply voltage to the output terminal. A third PMOS transistor outputs a second voltage lower than the power supply voltage to the output terminal. A well potential control section controls well voltages of the first and third transistors to be the power supply voltage where the power supply voltage and the second voltage are output to the output terminal, and controls the well voltages of the first and third transistors to be the first voltage where the first voltage is output to the output terminal.
