CD74HC4067 16-Channel Multiplexer Module – High-Speed Analog/Digital Breakout Board

The CD74HC4067 16-Channel Multiplexer Module is a versatile analog/digital breakout board designed for efficient signal routing and expansion in microcontroller projects. Acting like a 16-way rotary switch, it allows you to connect a single input/output pin to one of 16 channels using only 4 address lines, significantly reducing GPIO usage.

Ideal for both analog and digital applications, this module is perfect for connecting multiple sensors, reading analog values, or routing serial communication lines. With its bidirectional internal switches, low “on” resistance (~70Ω @ 4.5V), and support for voltages up to VCC, the CD74HC4067 ensures reliable performance and minimal signal interference. It also features a break-before-make design to prevent channel overlap and a dedicated enable pin to disable all channels at once when needed.
