Decoder circuit using transistors or diodes of different characteristics |
摘要 |
This invention is effective in the speeding up of a decoder circuit and maintenance of output amplitude. The invention is characterized in that, in a decoder circuit composed of a multi-emitter transistor or at least one diode group in which the anodes of a plurality of diodes are connected, and a charge circuit having an output emitter follower transistor, the multi-emitter transistor or the forward voltage of the diodes are larger than the voltage between the base and the emitter of the output emitter follower transistor.
