Bidirectional repeater circuits for bus-lines and the like are described which, when in idle condition, are capable of promptly transmitting binary data signals in either direction with amplification to restore wave form. A control signal is derived from each data signal during its transmission without imposing any time delay upon the transmission, and is used to disable temporarily signal transmission in the other direction. Thus, the repeater is self-contained in the sense of requiring no external control signal for controlling the direction of transmission. Capability for selectively disabling data transmission in both directions under external control can readily be incorporated in the circuits of the invention.
