Emitter Coupled Logic. As the current is steered between two legs of an emitter coupled pair ecl is sometimes called current steering logic csl current mode logic cml or current switch emitter follower csef logic. It is also called as current mode logic.
Emitter coupled logic is the fastest of all digital logic families. In electronics emitter coupled logic ecl is a high speed integrated circuit bipolar transistor logic family. Emitter coupled logic circuit ecl it has the highest speed of any of the currently available logic circuits.
It was invented by hannon s.
Emitter coupled logic ecl is a bjt based logic family which is generally considered as the fastest logic available. As the current is steered between two legs of an emitter coupled pair ecl is sometimes called current steering logic csl current mode logic cml or current switch emitter follower csef logic. Emitter coupled logic ecl is a bjt based logic family which is generally considered as the fastest logic available. Ecl achieves its high speed operation by employing a relatively small voltage swing and preventing the transistors from entering the saturation region.
