Assertion (A): Emitter - Coupled Logic (ECL) is the fastest of all logic families and used in applications where very high speed is essential.Reason (R): High speed in ECL is because the transistors are used in difference amplifier configuration in which they are never driven into saturation and the storage time is eliminated.
