What does the 74hc4067 16 channel multiplexer do?
That’s a mouthful – however in simple form it’s an IC that can direct a flow of current in either direction from one pin to any one of sixteen pins. Another way to think abou it is that you can consider the 74HC4067 to be a digital replacement to those rotary switches that allow you to select one of sixteen positions.
What kind of voltage does 74hc4067 microcontroller have?
At this point you should download the data sheet, as we refer to it through the course of the article. The first thing to note is that the 74HC4067 can operate on voltages between 2 and 6V DC, which allows use with 3.3V and 5V microcontrollers and boards such as Arduino and Raspberry Pi.
Can you use Paul Badger’s capacitive sensing library?
I’m trying to use the Capacitive Sensing Library by Paul Badger in conjunction with one or more 74HC4067 multiplexers to achieve a lot of capacitive touch inputs. I came across this youtube video where the poster seems to have accomplished what I’m trying but I can’t seem to replicate this.
Is there an Arduino library for 74hc4067?
Failed to load latest commit information. This is an Arduino library for interfacing the 74HC4067 multiplexers/demultiplexers. Class constructor. en is the Arduino pin to which the EN pin connects. s0 – s3 are the Ardunio pins to which the S1 – S3 pin connects.
Where is the power supply on the 74hc4067?
The power supply for the part is applied to pin 24, and GND to … pin 12. Pin 15 is used to turn the control the current flow through the inputs/outputs – if this is connected to Vcc the IC stops flow, and when connected to GND it allows flow.
Where are the control pins on the 74hc4067?
The sixteen inputs/outputs are labelled I0~I15. Finally there are the four control pins – labelled S0~S3. By setting these HIGH or LOW (Vcc or GND) you can control which I/O pins the current flow is directed through.
Can a 74hc4067 be used as a rotary switch?
Another way to think abou it is that you can consider the 74HC4067 to be a digital replacement to those rotary switches that allow you to select one of sixteen positions. Here’s an example of the SMD version:
