Abstract
When a signal A is input to a bi-directional buffer from a bus A, a first buffer detects the level of the signal A and supplies an OE control signal to a second buffer to disable an output therefrom. The output from the second buffer is set to a predetermined value by a bias circuit, and this predetermined value is supplied to the bi-directional buffer as a direction control signal via a direction designator together with output signal from the first buffer. In this circuit operation, when the signal A is input to the bi-directional buffer, it is immediately transmitted from the bus A side to the bus B side since the bi-directional buffer is set in an initial state by the bias circuit so as to transmit a signal in two directions.
