ABSTRACT:
A bidirectional buffer circuit includes a first terminal, a second terminal, a first output buffer to which a signal from the first terminal is input and which outputs the signal to the second terminal, a first one-shot buffer control circuit outputting a first control signal according to an earlier arriving signal out of a signal from the first terminal and a signal from the second terminal, a first one-shot buffer temporarily driving the second terminal by the first control signal, a second output buffer to which a signal from the second terminal is input and which outputs the signal to the first terminal, a second one-shot buffer control circuit outputting a second control signal according to an earlier arriving signal out of a signal from the first terminal and a signal from the second terminal, and a second one-shot buffer temporarily driving the first terminal by the second control signal.
