ABSTRACT:
In a system including several devices connected by means of a common data bus the adverse effects of reflections due to two or more devices simultaneously seeking access to the bus are minimized by confining such reflections to parts of the bus remote from the devices. This is achieved by preventing the amplitude of a signal at a receiving station on the bus from exceeding a predetermined level; and integrated circuit serving as a near ideal diode clamped to a reference voltage performs this function.
