Abstract

Cette invention a trait à un circuit opto-isolateur assurant l'isolation entre une ligne de transmission 12C bidirectionnelle et deux lignes de transmission unidirectionnelles. Ce circuit opto-isolateur comporte un port bidirectionnel recevant des données émanant de la ligne de transmission bidirectionnelle et envoyant des données à cette ligne. Il comporte, de plus, un trajet de sortie possédant, (i), un premier tampon recevant des données provenant du port bidirectionnel, (ii), un premier opto-isolateur recevant les données provenant d'une sortie du premier tampon et (iii), un deuxième tampon recevant des données provenant d'une sortie du premier opto-isolateur et fournissant ces données à un port de sortie. Le circuit comporte également un trajet d'entrée possédant, (i), un troisième tampon recevant des données provenant d'un port d'entrée, (ii), un second opto-isolateur recevant les données provenant d'une sortie du troisième tampon et (iii), un quatrième tampon recevant des données provenant d'une sortie du second opto-isolateur. Ce quatrième tampon fournit les données à l'arrivée au port bidirectionnel de façon que les caractéristiques de ces données soient compatibles avec les caractéristiques de la transmission 12C.
