Abstract

L'invention concerne les circuits logiques. Un circuit détecteur à deux états comprend en particulier deux transistors à effet de champ T1, T4, qui sont branchés en couplage croisé. Le canal de l'un des transistors est plus court que celui de l'autre, de façon que le circuit prenne un premier état prédéterminé en l'absence de signal d'entrée, et prenne l'autre état en présence d'un signal d'entrée approprié. Application à la conversion entre les niveaux TTL et les niveaux MOS.
