ABSTRACT:
An ECL-CMOS level converter circuit capable of operating at a high speed and having a simple structure, includes a bipolar differential amplifier and a level conversion.multidot.logic circuit. The bipolar differential amplifier inputting two voltages from two input terminal and a reference voltage from a reference voltage terminal includes at least two differential transistor parts each being composed of two bipolar transistors. The level conversion.multidot.logic circuit includes a MOS OR gate inputting one of differential output voltages output from each differential transistor part via two nodal points, a MOS AND gate inputting another of the differential output voltages output from differential transistor part via two nodal point, and a bipolar output transistor part inputting an OR output voltage and an AND output voltage from bases of high and low voltage side bipolar transistors, respectively, to output an output voltage from a connection point thereof.
