SmartElex Analog/Digital MUX Breakout - CD74HC4067

The SmartElex Analog/Digital MUX Breakout features the versatile CD74HC4067, a 16-channel multiplexer/demultiplexer that simplifies the connection of multiple sensors or devices to your microcontroller. Acting like a rotary switch, this chip routes a common pin (SIG) to one of 16 channel pins (CHANxx), allowing for seamless switching between analog and digital signals. With the ability to handle voltages up to VCC, this breakout is perfect for applications requiring low "on" resistance and minimal "off" leakage. Controlling the MUX is straightforward: simply connect four digital outputs to the address select pins (S0-S3) and send the binary address of the desired channel. This allows you to connect up to 16 sensors or devices using just five pins. The CD74HC4067 is particularly useful for routing TTL-level serial data, making it an excellent choice for applications involving multiple devices, I2C, or SPI communication. With its bidirectional internal switches and "break-before-make" switching to prevent crosstalk, the SmartElex breakout ensures reliable performance. Plus, the included "enable" pin allows you to completely disconnect the common pin when driven high, providing additional control over your connections.

Features:

  1. 16-Channel Multiplexer/Demultiplexer: Route signals between a common pin and up to 16 channels.
  2. Analog and Digital Signal Support: Works with both analog and TTL-level digital signals.
  3. Simple Control: Uses four digital outputs to select channels via address pins (S0-S3).
  4. Versatile Applications: Ideal for connecting multiple sensors or routing serial data.
  5. Low "On" Resistance: Ensures minimal signal loss and efficient switching.
  6. Bidirectional Switching: Supports connections in both directions for flexible use.
  7. Break-Before-Make Switching: Prevents crosstalk between channels for reliable operation.
  8. Enable Pin: Completely disconnects the common pin when driven high for added control.

Package Includes:

Setup Guide

1
Identify the pins
Locate VCC (power), GND (ground), and data pins (SDA/SCL for I2C, MOSI/MISO for SPI, or TX/RX for UART). Refer to the pinout diagram on the product page.
2
Wire to your microcontroller
Connect VCC to 3.3V or 5V (check the module spec), GND to GND, and data pins to the appropriate GPIO pins on your Arduino or Raspberry Pi.
3
Install libraries
In Arduino IDE, go to Sketch → Include Library → Manage Libraries and search for the sensor library. Install the recommended version.
4
Upload example sketch
Open File → Examples → [library name] → Basic Example. Upload to your board and open Serial Monitor to view output.
5
Calibrate if needed
Some sensors (temperature, humidity, distance) may need a short warm-up period or calibration. Run the calibration sketch if provided.
