In an input level converter for TTL--CMOS level conversion (or other conversion to CMOS) for an internal logic block operating with CMOS levels, an output transistor for executing the charge or discharge of the output capacitance thereof is formed of a bipolar transistor. Thus, the propagation delay times and their capacitance-dependencies of the input level converter can be lessened. Similarly, in an output level converter for CMOS--TTL level conversion (or other conversion from CMOS) for the internal logic block operating with the CMOS levels, an output transistor for executing the charge or discharge of the output load capacitance thereof is formed of a bipolar transistor. Thus, the propagation delay times and their capacitance-dependencies of the output level converter can also be lessened.
