摘要：
An ECL circuit wherein a current switch and an emitter follower are coupled, is so constructed that, in a standby mode, the current switch has its current cut off or rendered smaller than in an operating mode. In addition, the ECL circuit comprises means for decoupling a load resistance of the current switch and a base of the emitter follower in the case of cutting off the current of the current switch, or means for increasing the load resistance of the current switch in the case of rendering the current of the current switch smaller. The semiconductor circuit of the present invention can reduce the power consumption of the ECL circuit and can suppress fluctuations in the voltage levels of the outputs of the ECL circuit.
