The active-low enable inputs allow cascading of demultiplexers over many bits. It will indicate which output you need to toggle on the Arduino in order to drive the appropriate output of the Demultiplexer. And why are there 2 of them, you ask?

It requires a 32 LED chase array. You can upvote more than one answer. If you go through the datasheet of the IC, you will see a pinout section. Many TTL parts and older memory chips have active low enable inputs, so the active low outputs of this part can be connected directly to those inputs.

Post as a guest Name. Hi Sean, No, that would not work. Here is the truth table from the datasheet: First, the inversion of the outputs simply means that the output is active low.

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? Serial to Parallel Demultiplexer. Notify me of new posts by email. As for the NAND gates, there is a function being implemented in which the gates are there to realize it.

No, that would not work.

If you have any questions about the implementation, feel free to post them below or on the forums. This functionality is extremely simple to implement and can be a great alternative to shift registers discussed in one of my other tutorials. 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 47154n significant bits, with one ouput going to each of the other 16 s. EEEnthusiast May 12, at 8: 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 site?

My first question is more important June 23rd, dattasheet Comments. Rather than providing only a single enable, both pins are used. Leave A Comment Cancel reply Comment. The active-low output is just how the design for that specific decoder was datasheeg out – there is also active-high varieties. Sign up using Facebook. Keep in mind that my video showcases the hardware implementation of the IC before jumping into the Arduino Serial to Parallel implementation.
