Abstract
A monolithic, integrated ECL circuit, e.g., a decoder circuit for bipolar semiconductor stores, wherein a current supply transistor for the current supply of two digital stages is provided under the control of a semiconductor switching element which possesses two determinate switching states. In the first switching state of the semiconductor switching element one digital stage is connected to the current supply transistor and in the second switching state the other digital stage is connected to the current supply transistor.
