CD74HC4067 16 Channel Analog Digital Multiplexer Breakout Board Module

The CD74HC4067 operates like a 16-way electronic switch. It features 16 bidirectional I/O channels (C0–C15) connected internally to a common I/O pin (SIG). Using four select pins (S0–S3), you can quickly choose which of the 16 channels will be connected to the common pin.

The module supports both 3.3V and 5V logic, ensuring compatibility with a wide range of microcontrollers. It has extremely low on-resistance, low crosstalk, and fast switching capability, which makes it suitable for signal routing, multiplexed sensor inputs, and multi-point data acquisition.
