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

June 18th, 1 Comment. As for the NAND gates, there is a function being implemented in which the gates are there to realize it. 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.

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.
