Decoder circuit having selective transfer circuit for decoded output signal

摘要: A decoder circuit comprises a plurality of signal conductors, first potential setting units for the conductors to potential, second maintaining one conductor at and bringing remaining transfer transistors provided each conductor. gate electrode transistor is connected corresponding conductor, source thereof another switched ON decoded output when maintained brought potential. Therefore, only selected during operation without using discharge detecting non timing signal, thus an speed much higher decoding has simpler construction suitable as large scale integration circuit.
