I would like to appprentice even as you amend your website, how can i subscribe for a blog site? Hi, I am new to the Arduino, I have a project I am working on to test wiring harness.

Any pointers would be helpful. Home Questions Tags Users Unanswered.

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

It will indicate which output you need to toggle on the Arduino in order to drive the appropriate output of the Demultiplexer.

The active-low enable inputs allow cascading of demultiplexers over many bits. You can upvote more than one answer.

If you wanted to generate a 1 of demultiplexer, you could use 16 s looking at the 4 least significant bits, while a single would look at the 4 most significant bits, with one ouput going to each of the other 16 s.

The account aided me a acceptable deal. Sean Lovelady May 12, datasgeet 1: My first question is more important Make sure to fully understand what goes where and how everything is tied together internally.

And why are there 2 of them, you ask? It requires a 32 LED chase array. First, the inversion of the outputs simply means that the output is active low.

EEEnthusiast August 13, at 9: If you go through the datasheet of the IC, you will see a pinout section. According to the internal logic diagram on the datasheet, the G inputs are connected to a two-input AND gate with inverting inputs, whose output feeds one input of all the NAND gates that produce the outputs.

Here is the truth table from the datasheet: This means that you may not need the four push buttons if you 74145n want to work with the Arduino. Dayasheet as a guest Name.
