Abstract

L'INVENTION A POUR OBJET UN ELEMENT LOGIQUE A DEUX VITESSES DE COMMUTATION. CET ELEMENT COMPREND UN CIRCUIT D'ENTREE COMPRENANT DEUX TRANSISTORS A EFFET DE CHAMP DONT LES GRILLES RECOIVENT DES TENSIONS LOGIQUES, ET ALIMENTES EN PARALLELE PAR UNE SOURCE DE COURANT CONSTANT, CONSTITUEE PAR UN TROISIEME TRANSISTOR. LE CIRCUIT DE SORTIE COMPREND UN TRANSISTOR MONTE EN SOURCE ET UN DECALEUR DE TENSION. LA PARTICULARITE DE L'ELEMENT DE L'INVENTION EST QU'IL NE FONCTIONNE NI EN PORTE ET-OU, NI EN PORTE ET-NON MAIS EN PORTE A COINCIDENCES. L'INVENTION A POUR APPLICATION PRINCIPALE LES DIVISEURS DE FREQUENCE.
