ABSTRACT:
A buffer circuit outputs a low voltage and high voltages as opposed logic signals and a first high voltage and a second high voltage that is higher than the first high voltage as the high voltages. The buffer includes a logic control circuit, a first MOS transistor provided between a power supply for feeding the first high voltage and an output terminal, the first MOS transistor including a gate receiving a control signal of the first high voltage level outputted from the logic control circuit, and a backgate receiving the first high voltage, a second MOS transistor provided between a power supply for feeding the second high voltage and the output terminal, the second MOS transistor including a gate receiving a control signal of the second high voltage level outputted from the logic control circuit, and a backgate receiving the second high voltage, and a first switch circuit provided between the first MOS transistor and the output terminal and controlled ON/OFF state thereof by the control signal of the second high voltage level.
