I am a new user so I didn’t know I had that power. I would like to appprentice even as you amend your website, how can i subscribe for a blog site? Notify me of new posts by email.
The person who took time to answer the question will appreciate that. This allows more flexibility in the logic functions available. Home Questions Tags Users Unanswered. And why are there 2 of them, you ask?
Datasheet(PDF) – National Semiconductor (TI)
June 19th, 0 Comments. The active-low enable inputs allow cascading of demultiplexers over many bits. WhatRoughBeast 49k 2 28 No, that would not work. This functionality is extremely simple to implement and can be a great alternative to shift registers discussed in one of my other tutorials.
What you need to pay attention to as well is the truth table. June 30th, 0 Comments. If you go through the datasheet of the IC, you will see a pinout section. Post as a guest Name. Leave A Comment Cancel reply Comment.
June 14th, 0 Comments. This leads to possible outputs ranging from to on the 4 pins. Serial to Parallel Demultiplexer. The active-low output is just how the design for that specific decoder was carried out – there is also active-high varieties.
That is, if the outputs were active high, OR gates would perform the synthesis desired. Learn how your comment data is processed.
Use 4 Arduino pins for 16 outputs! Serial to Parallel Demultiplexer
Hi Sean, No, that would not work. Sign up using Email and Password. This section will describe each pin you will need to use. EEEnthusiast May 12, at 8: I graduated in and have tried my best to share my electrical knowledge and experience with viewers and readers from all over the world. The account aided me a acceptable deal.

A demultiplexer is a great way to allow you to use more output pins for your Arduino. I will go through the code section by section. Rather than providing only a single enable, datasheeet pins are used. First, the inversion of the outputs simply means that the output is active low.
Circuits Intégrés Logiques TTL
It requires a 32 LED chase array. As for the NAND gates, there is a function being implemented in which the gates are there to realize it.
