\u00a0Le 74HC4020\u00a0; Le 74HCT4020 est un compteur d’ondulation binaire \u00e0 14 \u00e9tages avec une entr\u00e9e d’horloge (CP), une entr\u00e9e de r\u00e9initialisation g\u00e9n\u00e9rale asynchrone (MR) et 12 sorties parall\u00e8les tamponn\u00e9es (Q0 et Q3 \u00e0 Q13). Le compteur avance sur la transition HAUT vers BAS du CP. Un niveau HAUT sur MR efface tous les \u00e9tages du compteur et force toutes les sorties au niveau BAS, ind\u00e9pendamment de l’\u00e9tat du CP. Chaque \u00e9tage de compteur est une bascule statique. Les entr\u00e9es incluent des diodes \u00e0 pince. Cela permet d’utiliser des r\u00e9sistances de limitation de courant pour interfacer les entr\u00e9es \u00e0 des tensions sup\u00e9rieures \u00e0 VCC.<\/span><\/div>\n
