Multiplexer

4-to-1 Multiplexer – Interactive

Set data inputs D₀–D₃ and select lines A, B. See each AND gate output (Y₀–Y₃) and final output Y.

D₀: 0

D₁: 0

D₂: 0

D₃: 0

A: 0

B: 0

AND gate outputs: 0 0 0 0

MUX Output Y: 0

Circuit Diagram

4:1 MUX with data inputs D₀–D₃, select lines A, B and output Y.

Timing Diagram

A and B cycle through 00, 01, 10 and 11 (t₀→t₃), showing which data line D₀–D₃ is selected and how Y follows it.

Current: t₀ (A=0, B=0, selected D₀, Y=0)
