    • In accordance with one aspect of the invention, a semiconductor integrated circuit is provided wherein an input circuit is formed by a phase split circuit having a bipolar transistor which outputs an inverted output from the collector and a 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. As a second aspect of the invention, a logic circuit is formed of a logic portion and an output portion. The output portion includes an emitter follower output transistor receiving an output signal generated by the logic portion and an active pull-down transistor receiving at its base a signal supplied thereto through a capacitance element. The signal received by the active pull-down transistor has a phase reverse to that of the input signal supplied to the base of said output transistor. Between the base and emitter of the active pull-down transistor, there is disposed a bias circuit formed of a transistor receiving at its base a predetermined bias voltage and an emitter resistor. Further, between a junction point of the emitter follower output transistor and the active pull-down transistor and the emitter of the transistor as a constituent of the bias circuit, there is disposed a capacitance element for feeding back the output signal.

    • A transistor circuit of this invention comprises a first transistor for receiving a first bias at its base, resistor means connected to the collector of the first transistor and clamp means connected to the junction between the first transistor and the resistor means, and obtains an output from a terminal of the resistor on the opposite to its junction with the first transistor. When a noise current due to .alpha. rays develops in the first transistor and the output is lowered, the clamp means operates in such a manner that the current flows through the clamp means and prevents the change of the output. The transistor circuit of this invention is connected to a resistor or a transistor and operates as a constant current circuit for supplying a current to the resistor or the transistor so that the current flowing therethrough becomes constant. For example, it is used as a constant current source of an emitter follower to constitute a level shift circuit. It is disposed in a feedback part and used as a constant current source in a logic circuit comprising a logic part consisting of a differential transistor circuit and the feedback part for negatively feeding back the in-phase output of the differential transistor circuit.
