Abstract

L'invention concerne un tampon bidirectionnel d'entrée/sor tie pour un système de microcalculateur. Ce dispositif comporte un étage d'attaque commandable 25 raccordé à une ligne d'introduction de données 21 par un registre tampon 23 et à un tampon de lecture 26 par l'intermé diaire d'une bascule bistable 24, elle-même reliée au registre tampon 23, et commandant la transmission ou l'arrêt de la transmission entre le registre tampon 23 et un bus 20 de transmission de données qui est relié au tampon de lecture 26 dont la sortie est raccordée à un poste d'entrée/sortie. Application notamment aux microcalculateurs.A bidirectional input / output buffer for a microcomputer system is disclosed. This device comprises a controllable drive stage 25 connected to a data input line 21 by a buffer register 23 and to a read buffer 26 by the intermediary of a flip-flop 24, itself connected to the register. buffer 23, and controlling the transmission or stopping of the transmission between the buffer register 23 and a data transmission bus 20 which is connected to the read buffer 26, the output of which is connected to an input / output station. Application in particular to microcomputers.
