The invention relates to an improved integrated injection logic circuit suitable for large scale integration. In integrated injection logic the fundamental circuit unit is a bipolar transistor having a unitary base and a unitary emitter with a plurality of electrically separate collectors used in combination with a complementary bipolar transistor for base current injection. Typically, the collector of the injector is integral with the base of the first transistor. By a novel symmetric arrangement of the individual collectors in respect to both base contacts and injectors, the response of the individual collectors is closely matched even at relatively high current levels.
