摘要： A bipolar/CMOS mixed type switching circuit comprising two npn-type bipolar transistors Q.sub.1, Q.sub.2 that are connected in the form of a totem pole in the output stage, a CMOS inverter and an NMOSFET M.sub.3 for driving these transistors in a complementary manner, and resistance means R for discharging the electric charge stored in the base of the transistor Q.sub.2. The threshold voltage of an NMOSFET M.sub.2 constituting the CMOS inverter in the absence of substrate effect is set to be substantially equal to the threshold voltage of the NMOSFET M.sub.3 in the absence of the substrate effect, and the channel conductance W.sub.N /L.sub.N of the NMOSFET M.sub.3 is so set that the threshold voltage V.sub.LT1 of the CMOS inverter and the practical threshold voltage V.sub.LT2 of the NMOSFET M.sub.3 will be nearly the same. Owing to the above structure, there is obtained a switching circuit which permits little through current to flow and which operates at high speeds.

摘要： 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.

摘要： An interface circuit capable of reliably transmitting signal even when there is fluctuation in the potential difference in reference potentials between circuits between which signal transmission is carried out. An interface circuit 4 is comprised of a level shift circuit 20 and a potential selection circuit 10 for selecting the potential of a power supply voltage for operating the level shift circuit 20. The potential selection circuit 10 selects one of a plurality of input potentials. The level shift circuit 20 receives a voltage pulse having a first potential as reference potential and outputs a voltage pulse having a second potential as reference potential. The level shift circuit 20 is operated on the basis of both a potential difference between the output potential from the potential selection circuit and the first potential and a potential difference between the selected potential and the second potential.
