Abstract

Abstract Translated from German Die in ECL-Schaltungen üblichen UND-Verknüpfungen durch Seriesgating beschränken die Anzahl der Eingangsvariblen auf die Anzahl der möglichen Seriesgating-Stufen, also maximal drei Stufen. Die Erfindung realisiert durch schaltungstechnische Maßnahmen zusätzliche UND-Verknüpfungen zwischen Eingangsvariablen und ermöglicht pro Gatter mehr als drei Eingangsvariablen und damit kürzere Signallaufzeiten. The AND gates in series gating that are common in ECL circuits limit the number of input variables to the number of possible series gating stages, i.e. a maximum of three stages. The invention realizes additional AND operations between input variables by means of circuitry measures and enables more than three input variables per gate and thus shorter signal transit times.
