Two important points concerning emitter- coupled logic are:
A) the output voltage levels are the same as the input logic levels and the two outputs are in phase with each other.
B) the output voltage levels are not the same as the input logic levels and the two outputs are complements of each other.
C) the output voltage levels are not the same as the input logic levels and the two outputs are in phase with each other.
D) the two output voltage levels are the same as the input logic levels and the two outputs are complements of each other.

Question

Quizplus · Accepted Answer

Emitter-coupled logic (ECL) is known for its high speed, but one of its characteristics is that the output voltage levels are not the same as the input logic levels due to the voltage drop across the transistors in the circuit. Additionally, ECL provides two outputs that are complements of each other, which is useful for certain types of digital logic circuits where both the true and complemented forms of a signal are needed.
