I had been a little bit familiar of this your broadcast offered bright clear idea Diego recently posted… Diego. As for the NAND gates, there is a function being implemented in which the gates are there to realize it. And why are there 2 of them, you ask?

Since the ouputs are active low, NAND gates do the job. I would like to appprentice even as you amend your website, how can i subscribe for a blog datashee

Email Required, but never shown. Here is the truth table from the datasheet: A demultiplexer is a great way to allow you to use more output pins for your Arduino. This functionality dxtasheet extremely simple to implement and can be a great alternative to shift registers discussed in one of my other tutorials.

This section will describe each pin you will need to use. Please consider upvoting those questions you found useful like this one by clicking the arrow pointing up near the answer vote count which is in turn above the checkbox you clicked to accept this question. Will someone please explain the purpose of inverting the outputs 0 through 15 as well as the use the NAND gates here? The active-low output is just how the design for that specific decoder was carried out – there is also active-high varieties.

EEEnthusiast August 13, at 9: If you go through the datasheet of the IC, datashset will see a pinout section. Notify me of new posts by email. No, that would not work. Learn how your comment data is processed. Sign up using Email and Password. All the other ouputs stay high.

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.

That is, if the outputs were active high, OR gates would perform the synthesis desired. First, the inversion of the outputs simply 744154n that the output is active low.

Paul Johnosn August 1, at 5: If you want to know exactly what is going on then draw out the truth table, but it is unlikely their function will make much sense to you. I am making a Jupiter II model, and want to build the fusion core for the bottom of it. June 18th, 1 Comment. Serial to Parallel Demultiplexer. My first question is more important There are probably two enable inputs because otherwise there would be two unused pins on the 24 pin package I don’t recall seeing 22 pin DIP packages.

It requires a 32 LED chase array. I will go through the code section by section.
