Abstract
A compound transistor type inverter, i.e., comprised of MIS and bipolar transistors, including, at the output stage thereof, an npn transistor operative to charge a load. The npn transistor can be quickly cut OFF by an additional transistor, and simultaneously, the additional transistor is operative to attain a quick discharge from the load. Still another additional transistor is employed, in a case where the inverter includes a pnp transistor, other than the npn transistor, at a ground side, which another additional transistor is operative to bypass the collector and emitter of the pnp transistor.
