Will someone please explain the purpose of inverting the outputs 0 through 15 as well as the use the NAND gates here? That is, for an input ofthe 0 output is selected, and it is driven low. Use 4 Arduino pins for 16 outputs! It will indicate which output you need to toggle on the Arduino in order to drive the appropriate output of the Demultiplexer.
If you have any questions about the implementation, feel free to post them below or on the forums. I will go through the code section by section. Email Required, but never shown. This means that you may not need the four push buttons if you only want to work with the Arduino.
National Semiconductor – datasheet pdf
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. All the other ouputs stay high. This allows more flexibility in the logic functions available.

Use 4 Arduino pins for 16 outputs! Serial to Parallel Demultiplexer
That is, if the outputs were active high, OR gates would perform the synthesis desired. Rather than providing only a single enable, both pins are used. If you are looking for a different way datashert drive your outputs, or want an easier solution to your output needs, this tutorial is definitely for you.

You can upvote more than one answer. Make sure to fully understand what goes where and how everything is tied together internally. I am making a Jupiter II model, and want to build the fusion core for the bottom of it. I would like to appprentice even as you amend your website, how can i subscribe adtasheet a 74154h site? WhatRoughBeast 49k 2 28 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. Hi, I am new to the Arduino, I have a project I am working on to test wiring harness.
No, that would not work.
June 19th, 0 Comments. The account aided me a acceptable deal.
And why are there 2 of them, you ask? I was wondering if you can control multiple 74hc with the 74lsn.
Hi Sean, No, that would not work.
