ABSTRACT:
An I.sup.2 L logic circuit provided with a logic section which includes at least one I.sup.2 L unit circuit formed of a transistor for injector and a driving transistor.
The I.sup.2 L logic circuit is further provided with a supply circuit for supplying the I.sup.2 L unit circuit with an injector current corresponding to a control signal. The supply circuit is formed of a first circuit for steadily supplying the I.sup.2 L unit circuit with a predetermined injector current, and a second circuit for supplying the I.sup.2 L unit circuit with another injector current in accordance with the control signal, the first and second circuits being connected in parallel with each other.
