The circuit configuration for converting logic levels has a bipolar input stage and a CMOS output stage. The bipolar input stage is equipped to process ECL and CML logic levels. The CMOS-logic output stage is equipped to supply trailing CMOS gates having CMOS logic levels. A difference amplifier includes bipolar transistors, which are connected to a common emitter current source and to separate collector current sources. An input-output feedback CMOS inverter is connected to one of the collectors, and the output of the inverter is coupled to an output node.
