Use 4 Arduino pins for 16 outputs! Serial to Parallel Demultiplexer

The account aided me a acceptable deal. I am a new user so I didn’t know I had that power. Hi, I am new to the Arduino, I have a project I am working on to test wiring harness.

If you go through the datasheet of the IC, you will see a pinout section.

All the other ouputs stay high. I had been a little bit familiar of this your broadcast offered bright clear datashet Diego recently posted… Diego.

WhatRoughBeast 49k 2 28 Hi Sean, No, that would not work. Rather than providing only a single enable, both pins are used. I will go through the code section by section. This leads to possible outputs ranging from to on the 4 pins. This functionality is extremely simple to implement and can be a great alternative to shift registers discussed in one of my other tutorials.

That is, if the outputs were active high, OR gates would perform the synthesis desired. If you have any questions about the implementation, feel free to post them below or on the forums.

4 to 16 decoder logic diagram – Electrical Engineering Stack Exchange

Many TTL parts and older memory chips have active low enable inputs, so the active low outputs of this part can be connected directly to those inputs. Learn how your comment data is processed. This allows more flexibility in the logic functions available. Diego July 26, at 5: I am making a Jupiter II model, and want to build the fusion core for dataseet bottom of it. Its purpose is to take a Serial signal and convert it to a parallel one.

June 30th, 0 Comments. Will someone please explain the purpose of inverting the outputs 0 through 15 as well as the use the NAND gates here?

Since the ouputs are active low, NAND gates do the job. Serial to Parallel Demultiplexer. I graduated in and have tried my best to share my electrical knowledge and experience with viewers and readers from all over the world. June 19th, 0 Comments. Email Required, but never shown.

A demultiplexer is a great way to allow you to datashset more output pins for your Arduino. No, that would not work. You can find me on my personal site or LinkedIn!
