Abstract

A device for two-way digital transmission on a bus having at least one two-way line. The device includes a first pulling device for pulling a first section of the line to a first logic level, a second pulling device for pulling a second section of the line to the first logic level, and at least one two-way repeater that is connected between the first section and the second section. The repeater includes a third pulling device for pulling the first section of the line to a second logic level, a fourth pulling device for pulling the second section of the line to the second logic level, and a logic circuit that prevents the third and fourth pulling devices from being simultaneously active. In one preferred embodiment, at least one electronic circuit is connected to the first section of the line and at least one other electronic circuit is connected to the second section of the line. In another preferred embodiment, the repeater also includes a conditional circuit that is controlled by an electronic circuits connected to the first section. The conditional circuit selectively enables or prevents transmission between the first and second sections of the line.
