SparkFun CD74HC4067 Analogue/Digital MUX Breakout Board
Versatile 16-channel analogue/digital MUX breakout board for expanding I/O capabilities in electronics projects.
The SparkFun CD74HC4067 Analogue/Digital MUX Breakout Board provides a simple and convenient interface for the CD74HC4067 16-channel analogue/digital multiplexer/demultiplexer. This versatile chip functions like a rotary switch, routing the common pin to one of the 16 channel pins as required, making it ideal for expanding your project's I/O capabilities without increasing pin count significantly.
Designed for both digital and analogue signals, the board features a bi-directional design, allowing connections to function in either direction. Controlling the chip is straightforward—simply connect four digital outputs to the S0-S3 pins and send the binary address of the desired channel.
Key Features:
- Bi-directional operation for flexible signal routing
- 16-channel multiplexing allows connection of up to 16 sensors using just 5 pins
- Wide voltage support between ground and VCC
- Low 'on' resistance and 'off' leakage for efficient performance
- Enable pin included—drive it high to disconnect the common pin (all switches 'off')
Applications:
This breakout board is perfect for projects requiring multiple sensor inputs or signal routing, such as data acquisition systems, automation projects, and homebrew electronics. Its compact design and ease of use make it a must-have for hobbyists and professionals alike.
