How many address lines would be needed for an 8 line MU?
- 2.
- 3.
- 4.
Explanation
An eight-line multiplexer needs three address lines because two raised to the third power equals eight, giving exactly eight unique select combinations. Two lines address only four inputs, and four lines would address sixteen.
