More Information
Summary:The disclosure relates to coupling point switches in ECL technology. The coupling point switches are each formed by means of a differential amplifier circuit with two emitter-coupled high frequency transistors; in order to reduce the power consumption, a switching transistor is inserted in the common emitter current circuit, the switching transistor only being conductive when the appertaining coupling point is driven into the through-connected condition. The disclosure can particularly be employed in the distribution of video signals.
