The CD74HC4067 16-Channel Analog/Digital Multiplexer Breakout Board is a compact input/output expansion module compatible with Arduino, ESP32, and Raspberry Pi. It functions like a digitally controlled rotary switch, allowing you to connect up to 16 individual signals (C0–C15) to a single microcontroller pin (SIG) using only 4 selection lines (S0–S3). Because it is fully bidirectional, it works seamlessly for both reading analog/digital sensors and controlling output components like LEDs or relays across a standard 2V to 6V operating range.

CD74HC4067 16-Channel Analog/Digital Multiplexer Breakout Board.
The CD74HC4067 16-Channel Analog/Digital Multiplexer Breakout Board is a highly versatile electronic module designed to expand the input and output capabilities of any microcontroller, such as an Arduino, ESP32, Raspberry Pi, or STM32. It functions as a digitally controlled rotary switch that routes a single common signal pin (SIG) to any one of 16 individual channel pins (C0 through C15).
This module works seamlessly with both analog and digital signals. It is bidirectional, meaning current can flow in either direction. This allows you to use the breakout board to read 16 distinct analog sensors (like potentiometers or photoresistors), or to drive 16 digital devices (such as LEDs or relays) using only a few control pins from your master controller.

Core Features & Technical Specifications
- Wide Input Voltage Range: Supports operation between 2.0V to 6.0V, making it perfectly compatible with both 3.3V and 5V logic controllers.
- Low On-Resistance: Features low internal switch resistance (typically 70 Ohms at 4.5V), ensuring minimal signal degradation or voltage drop when reading analog sensors.
- High-Speed Switching: Fast propagation delay allows for rapid transitions between channels, making it suitable for quick data acquisition.
- Bidirectional Operation: Can route an input signal to one of 16 targets, or multiplex 16 input sources into a single common terminal.
- Enable Control (EN Pin): Features a dedicated active-LOW break-before-make enable pin. Pulling this pin HIGH completely disconnects the common pin from all channels, useful for cascading multiple boards.

Pin Functionality Overview
- Signal (SIG) Pin: The common junction point. Connect this to an analog read pin or digital pin on your microcontroller.
- Channel Pins (C0 – C15): The 16 individual lanes connected to your peripheral devices, components, or sensors.
- Selection Pins (S0 – S3): Four digital address lines used to control the state of the multiplexer. By applying a binary combination (LOW/HIGH) across these four pins, you choose which specific channel connects to the SIG line.
- Power Pins (VCC / GND): Connect to your system’s power rail and ground to power the internal CMOS logic chip.
