Abstract
Un circuit à bascule comprend une partie maître et une partie esclave 10, 20 et réagit à des signaux d'entrée de données J, K ainsi qu'à des signaux d'horloge vrais et complémentaires CL, CL. La partie maître 10 comprend trois portes OU 12, 16, 18 et une porte OU supplémentaire 14 qui est indépendante des signaux d'horloge. Les sorties des quatre portes OU sont connectées à un circuit ET câblé 30 pour fournir un signal de sortie maître Q qui est connecté à la partie esclave 20. La partie esclave 20 comprend deux portes OU 22, 26 ainsi qu'une porte OU supplémentaire 24 pouvant être commandée indépendamment des signaux d'horloge, les sorties vrais des trois portes OU 22, 24, 26 étant couplées à un circuit ET câblé 32 pour fournir un signal de sortie de bascule Qo et les sorties complémentaires étant couplées à un circuit OU câblé 34 pour fournir un signal de sortie complémentaire Qo .
