WebOct 6, 2024 · Emitter-coupled logic (ECL) family is a logic family that makes use of differential amplifiers operating in their active mode for the construction of logic gates. Figure 3.49 shows the circuit diagram of an OR-NOR gate using ECL. This is the basic gate in the ECL family.
WebEmitter-coupled logic (ECL) is a high-speed logic circuit family of bipolar junction transistors (BJTs). ECL ICs (integrated circuits) achieve high-speed performance because BJTs never operate in the saturation mode and storage time delays are avoided. WebJul 12, 2024 · Emitter-coupled logic (ECL) is a BJT-based logic family which is generally considered as the fastest logic available. ECL …
WebEmitter-Coupled Logic (ECL): The ECL family is the fastest logic family in the group of bipolar logic families. The characteristic features that give this logic family its high speed or short propagation delay are outlined as follows: It is a nonsaturating logic.
