An active pull-down emitter coupled logic circuit includes a high voltage line, a low voltage line, a first constant current circuit coupled to the low voltage line, first and second main current paths extending between the high voltage line and the first constant current circuit, and first and second subordinate current paths extending between the high voltage line and the first constant current circuit. The subordinate current paths are paired with their respective ones of the main current paths.
