WebA1: ECL stands for Emitter Coupled Logic. The basic circuit configuration consists of a pair of NPN transistors with their emitters connected together and fed by a current source as show in Fig. 1. Q 1 and Q 2 are normally referred to as the differential switch. WebEmitter-coupled logic is the best BJT-based logic family used in the conventional logic-system design. Sometimes, it is also called current mode logic which is a very high …

ECL is based on an emitter-coupled (long-tailed) pair, shaded red in the figure on the right. The left half of the pair (shaded yellow) consists of two parallel-connected input transistors T1 and T2 (an exemplary two-input gate is considered) implementing NOR logic. The base voltage of the right transistor T3 is held fixed … See more In electronics, emitter-coupled logic (ECL) is a high-speed integrated circuit bipolar transistor logic family. ECL uses an overdriven bipolar junction transistor (BJT) differential amplifier with single-ended input and limited … See more The ECL circuit operation is considered below with assumption that the input voltage is applied to T1 base, while T2 input is unused or a … See more ECL circuits usually operate with negative power supplies (positive end of the supply is connected to ground). Other logic families ground the negative end of the power supply. This is done mainly to minimize the influence of the power supply variations on the … See more • Motorola MECL logic family datasheets, 1963 See more ECL was invented in August 1956 at IBM by Hannon S.
