Abstract
A pulse output circuit which has an output stage connected to a capacitive load capable of improving a through-rate of an input pulse signal with reduced power consumption is provided. A circuit having a first transistor which is supplied with a base current at its base in accordance with an input pulse signal from an input terminal, which is supplied with a power source voltage at the collector, which has an emitter connected to the output terminal, and which supplies current to a capacitive load; a third transistor which has a collector connected to the emitter of the first transistor and which has an emitter which is grounded; a bias means which supplies a predetermined base current to the base of the third transistor to make it conductive; and a differentiating circuit which outputs a signal to reduce the base current of the second transistor at the rising edge of the pulse to make it non-conductive and to increase the base current of the second transistor at the trailing edge of the pulse to increase the current.
