Abstract

UN CIRCUITO REGULADOR PARA SU USO ENTRE UNA LINEA DE BUS DE COLECTOR ABIERTO BIDIRECCIONAL (4) Y UN DISPOSITIVO (D) CAPAZ DE LEER EL ESTADO DE LA LINEA DEL BUS Y EXCITARLO DEBILMENTE. EL DISPOSITIVO TIENE UN SOLO TERMINAL DE ENTRADA/SALIDA (1) AL CUAL ESTA CONECTADO A LA LINEA (7) DEL CIRCUITO REGULADOR. EL CIRCUITO REGULADOR ESTA COMO PARA DISTINGUIR ENTRE TRES NIVELES LOGICOS EN LA LINEA, Y EN PARTICULAR ENTRE DOS NIVELES BAJOS LOGICOS (U{SUB,A}, U{SUB,B}), QUE CORRESPONDEN AL DISPOSITIVO (1) O AL REGULADOR DE ENTRADA (C1) QUE EXCITA DEBILMENTE LA LINEA DEL BUS. LOS REGULADORES DE ENTRADA Y SALIDA ESTAN COMPRENDIDOS POR COMPARADORES RESPECTIVOS (C1,C2). LA TENSION DE REFERENCIA PARA EL COMPARADOR DEL REGULADOR DE SALIDA UBICADA ENTRE U{SUB,A} Y U{SUB,B}, POR MEDIO DE LA CUAL SE CONSIGUE LA DISTINCION ENTRE LAS MISMAS. CUANDO EL COMPARADOR DEL REGULADOR DE SALIDA DETECTA U{SUB,A} PROVOCA QUE LA LINEA DEL BUS (4) SEA EXCITADA DEBILMENTE.
