Abstract
A circuit for driving a transmission line composed of first and second conductors, comprises input transistors for providing a differential signal, and first and second output transistors having their bases connected to receive the differential signal, their collectors connected to a first reference potential level, and their emitters connected to the first and second conductors respectively. An output enable circuit selectively places the output transistors either in a conductive condition, in which they apply the differential signal to the transmission line, or in a non-conductive condition, in which the isolate the transmission line from the input transistors.
