Abstract
An emitter-coupled logic circuit having superior drivability, stable operation, and obtaining complementary outputs. A pair of input differential transistors have their emitters coupled to a first current source in common, their bases connected to receive respective input signals, and outputting complementary logic values corresponding to the respective input signals. 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 transistors and their emitters are connected to the respective output terminals. The bases of the pull-down transistors are supplied with the respective input signals, their emitters are coupled to a second current source in common, and their collectors are connected to the respective output terminals. A stabilizing circuit is connected to the respective output terminals to maintain the pull-up transistors in conducting states.
