ECL’s major disadvantage is that __________
A. It requires more power
B. It’s fanout capability is high
C. It creates more noise
D. It is slow
Answer:A
ECL’s major disadvantage is that __________
A. It requires more power B. It’s fanout capability is high C. It creates more noise D. It is slow
Explanation: ECL’s major disadvantage is that each gate continuously draws current, which means it requires (and dissipates) significantly more power than those of other logic families. But ECL logic gates have clock frequency. Thus, they have a fast operation.
