Abstract
A semiconductor integrated circuit wherein an input circuit is formed by a phase split circuit consisting of a bipolar transistor which outputs an inverted output from the collector and non-inverted output from the emitter, the emitter follower output circuit is driven by an inverted output of the phase split circuit, meanwhile, an emitter load of the emitter follower output circuit is formed by a transistor, and the emitter load transistor is temporarily driven conductively by a charging current of the capacitance to be charged by the rising edge of the non-inverted output of the phase split circuit.
