CD74HC4067 16-Channel Analog/Digital Multiplexer Breakout Board Module

The CD74HC4067 16-Channel Analog/Digital Multiplexer Breakout Board Module provides a compact, easy-to-integrate solution for routing any one of sixteen input channels to a single output. Based on the high-speed CMOS CD74HC4067 chip, the module supports both analog and digital signals and is designed to simplify expansion of input/output capacity in microcontroller, measurement, and control applications.

Key features:

• Selectable routing of analog or digital signals through a single channel using addressing pins.
• Simple pinout for channel select lines, VCC and GND to facilitate wiring and rapid prototyping.
• Low on-resistance and limited crosstalk thanks to high-speed CMOS switching characteristics.
• Compact form factor compatible with breadboards and enclosed test fixtures for convenient installation.
• Suitable for integration with popular microcontrollers to expand sensing and switching capabilities.

Common use cases include connecting multiple sensors to a single analog-to-digital converter input, switching between multiple signal sources for test and troubleshooting, and automating multi-channel measurement tasks in laboratory or industrial setups. The module reduces the required number of input pins while preserving signal fidelity and switching speed.

The breakout board’s straightforward layout and reliable switching behavior reduce cable complexity in multi-channel systems and make the CD74HC4067 module a practical choice for developers, engineers, and hobbyists who need flexible and dependable signal routing in compact projects.
