Diego July 26, at 5: Make sure to fully understand what goes where and how everything is tied together internally. I am a new user so I didn’t know I had that power. datasheey

The active-low output is just how the design for that specific decoder was carried out dtaasheet there is also active-high varieties. Leave A Comment Cancel reply Comment. If you wanted to generate a 1 of demultiplexer, you could use 16 s looking at the 744154n 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.

Rather than providing only a single enable, both pins are used. No, that would not work. If you have any questions about a specific segment, leave them in a comment below or on the forums.

June 19th, 0 Comments. That is, for an input ofthe 0 output is selected, and it is driven low. Sign up using Email and Password. Any pointers would be helpful. Hi Sean, No, that would not work.

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. Notify me of follow-up comments by email. I had been a little bit familiar dwtasheet 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. It will indicate which output you need to toggle on the Arduino dataseet order to drive the appropriate output of the Demultiplexer.

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

If you are looking for a different way to drive your outputs, datasheett want an easier solution to your output needs, this tutorial is definitely for you.

Use 4 Arduino pins for 16 outputs! I would like to appprentice even as you amend your website, how can i subscribe for a blog site? Here is the truth table from the datasheet: This allows more flexibility in the logic functions available. I was wondering if you can control multiple 74hc with the 74lsn. Its purpose is to take a Serial signal and convert it to a parallel one.

If you go through the datasheet of the IC, you will see a pinout section. First, the inversion of the outputs simply means that the output is active low.

The account aided me a acceptable deal. Notify me of new posts by email. If you have any questions about the implementation, feel free to post them below or datwsheet the forums.

Serial to Parallel Demultiplexer. You can find me on my personal site or LinkedIn! Sorry, I just stuck with the defaults of that addon. I will go through the code section by section.

The person who took time to answer the question will appreciate that. June 23rd, 0 Comments. Since the ouputs are active low, NAND gates do the job. So is it possible that both enables are hooked to a 2-input OR gate; this is just making use of the extra pins to make 24? datashset

This leads to possible outputs ranging from to on the 4 pins. The active-low enable inputs allow cascading of demultiplexers over many bits. Keep in mind that my video showcases the hardware implementation of the IC before jumping into dataxheet Arduino Serial to Parallel implementation. Learn how your comment data is processed.

Hi, I am new to the Arduino, I have a project I am working on to test wiring harness. That is, if the outputs were active high, OR gates would perform the synthesis desired.
