摘要:
Provided is a voltage selection circuit for outputting a potential selected from a plurality of input potentials, the voltage selection circuit capable of selectively outputting a first high-level potential being a highest potential, a second high-level potential, or a third high-level potential being a lowest potential from an output terminal thereof. The voltage selection circuit includes a first switching circuit that supplies the first high-level potential to the output terminal, a second switching circuit that supplies the second high-level potential to the output terminal, and a third switching circuit that supplies the third high-level potential to the output terminal. The first switching circuit includes a high-voltage transistor and a level shifter connected to a gate terminal of the high-voltage transistor. The second switching circuit includes a first low-voltage transistor, a level shifter connected to a gate terminal of the first low-voltage transistor, and a diode disposed between the first low-voltage transistor and the output terminal. The third switching circuit includes a second low-voltage transistor and a diode disposed between the second low-voltage transistor and the output terminal.
