Thread: What is the difference between saturation and non-saturation logic?

It will also be helpful if you can describe the two. All I know is that these two are characteristics of logic families under switching transistor circuits.

I think it's speed. Non saturation logic is faster than saturated logic.


Emitter coupled logic (ECL) is a non saturated logic, which means that transistors are prevented from going into deep saturation, thus eliminating storage delays. Preventing the transistors from going into saturation is accomplished by using logic levels whose values are so close to each other that a transistor is not driven into saturation when its input switches from low to high. In other words, the transistor is switched on, but not completely on. This logic family is faster than TTL.
