Abstract
First emitters of a pair of input multi-emitter transistors are connected to a current source in common, to form an input differential amplifier. The other emitters of the input multi-emitter transistors are connected to current sources respectively. Pull-up and pull-down transistors are provided for respective ones of a pair of output terminals. Bases of the pull-up transistors are supplied with collector voltages of the input multi-emitter transistors, while those of the pull-down transistors are supplied with voltages of the other emitters of the multi-emitter transistors. Provided is an emitter-coupled logic circuit which has excellent load drivability, operates stably and obtains complementary outputs at a low cost.
