摘要：
An ECL flip-flop circuit has a data holding differential transistor pair and a feedback circuit provided between the collectors and bases of this differential transistor pair. The feedback circuit includes a resistor connected between the bases of the data holding differential transistor pair, a pair of switching means for selectively terminating one end or the other of the resistor, and a pair of feedback transistors each adapted to receive at its base the collector potential of one transistor or the other of the differential transistor pair and to form an emitter follower circuit with the resistor selectively included therein. Thus, it is possible to prevent a malfunction of the ECl flip-flop circuit due to .alpha.-particles or the like.
