Abstract
A buffer circuit capable of switching between input mode and output mode includes a first transistor for outputting a prescribed voltage to an input/output terminal depending on a conductive state during the output mode of the buffer circuit, a pre-driver for controlling the conductive state of the first transistor during the output mode of the buffer circuit, and a power supply circuit for providing a first power supply to the pre-driver during the output mode of the buffer circuit and providing or blocking the first power supply to the pre-driver in accordance with an input voltage to the input/output terminal during the input mode of the buffer circuit.
