Abstract
L'invention concerne un compteur binaire synchrone. Le compteur comprend des étages 200, 201, 202, 203 qui subissent un changement d'état lors de l'application d'un signal de basculement. Un circuit porte formé de transistors est monté entre les étages successifs et, lorsque l'étage précédent est dans un premier état, le signal de basculement est transmis aux étages suivants alors que, lorsque l'étage correspondant du compteur est dans un second état, le transfert du signal de basculement est interrompu. Application à la réalisation de compteurs binaires synchrones sous forme de circuits intégrés.
