ABSTRACT An integrated logic circuit has an epitaxial layer arranged on a substrate consisting of semiconductor material. An emitter zone, an output collector zone and at least one additional collector zone are provided in the epitaxial layer. A lateral pnp transistor and a vertical, inversely operated npn transistor are provided with the epitaxial and zone structure such that the emitter of the lateral transistor is connected to a supply line, the out- put collector of the lateral transistor is simultaneously the base of the ver- tical transistor, the collector terminals which represent the outputs of the vertical transistor are provided for taking off output signals and the supply potential is connected across the supply line and the epitaxial layer which contains the base terminal of the lateral transistor and the emitter terminal of the vertical transistor.
