Decoder

3-to-8 Decoder – Interactive

Set X, Y, Z and observe which output D0–D7 becomes 1.

X: 0

Y: 0

Z: 0

Outputs: 0 0 0 0 0 0 0 0

Circuit Diagram

3:8 decoder using AND gates with inputs X, Y, Z.

Timing Diagram

Inputs X, Y, Z count from 000 to 111 (t₀–t₇); only one D output is high.

Current: X Y Z = 000 (active output: D0)
