Multiplexer against Decoder, side by side.

Both scale badly: each extra select line doubles a decoder's outputs and doubles a multiplexer's data inputs.

Questions about the Mux & Decoder poster

What’s on the Mux & Decoder poster?
Multiplexer against Decoder, side by side. Multiplexer: Many inputs, one output; Multiplexer: n select lines choose one of 2ⁿ inputs; Multiplexer: Used to share a bus or a resource; Multiplexer: Can implement any logic function; Multiplexer: A demultiplexer is the reverse; Decoder: One input code, many outputs; Decoder: n inputs drive 2ⁿ outputs, one active; Decoder: Used for addressing and chip select; Decoder: An enable pin gates the whole device; Decoder: An encoder is the reverse; A decoder plus an OR gate builds any sum of products; a multiplexer reaches the same…. Both scale badly: each extra select line doubles a decoder's outputs and doubles a multiplexer's data inputs.
Who is the Mux & Decoder poster for?
Mux & Decoder belongs to the Electrical Engineering section rather than to a school year, because engineering is not something one grade owns. Anyone learning digital logic can pin it up — a beginner, a student mid-course, or someone revising years later.
When should you use the Mux & Decoder poster?
Recognise which one a datasheet block is, and its pin count explains itself. A wall chart earns its place by being glanceable from where the work is happening, so Mux & Decoder belongs on the wall where that engineering work actually happens, within glancing distance, rather than filed away.
What other posters go with Mux & Decoder?
Adders, Boolean Algebra and Counters & Registers sit alongside Mux & Decoder in the Electrical Engineering section. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.AddersBoolean AlgebraCounters & Registers
Is the Mux & Decoder poster free to download and print?
Yes. Mux & Decoder downloads as a free PDF with no account, no email and no watermark, like everything else in the Electrical Engineering section. Print as many copies as you like for a home, a classroom, a library or a tutoring group; reselling the file is the only thing the licence rules out.Read the licence
What size does the Mux & Decoder poster print at?
Mux & Decoder is a vector PDF laid out for US Letter, and prints on A4 with Fit to page — the same file, no separate download. Because every mark on it is drawn rather than photographed, it stays sharp enlarged to A3, A2 or A1 at a copy shop. Colour carries emphasis only, so a greyscale print of Mux & Decoder loses nothing.Printing guide
