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.

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

Post as a guest Name. Keep in mind that my video showcases the hardware implementation of the IC before jumping into the Arduino Serial to Parallel implementation. Rather than providing only a single enable, both pins are used. 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. That is, for an input ofthe 0 output is selected, and it is driven low. If you are looking for a different way to dataheet your outputs, or want an easier solution to your output needs, 74154b tutorial is definitely for you.

If you go through the datasheet of the IC, you will see a pinout section. Sean Lovelady May 12, at 1: 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.

Will someone fatasheet explain the purpose of inverting the outputs 0 through 15 as well as the use the NAND gates here?

This functionality is extremely simple to implement and can be a great alternative to shift registers discussed in one of my other tutorials. This means that you may not need the four push buttons if you only want to work with the Arduino.

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 74154nn 16 s. I am a new user so I didn’t know I had that power. Here is the truth table from the datasheet: This leads to possible outputs ranging from to on the 4 pins.

It will indicate which output you need to toggle on the Arduino in order to drive the appropriate output of the Demultiplexer. This allows more flexibility in the logic functions available.

Paul Johnosn August 1, at 5: I would like to appprentice even as you amend your website, how can i subscribe for a blog site? A demultiplexer is a great way to allow you to use more output pins for your Arduino. The active-low enable inputs allow cascading of demultiplexers over many bits.

I was wondering if you can control multiple 74hc with the 74lsn.
