- The CD74HC4067 is a versatile 16-channel analog/digital multiplex/demultiplex breakout board, allowing for seamless processing of both digital and analog signals. It facilitates the connection of up to 16 sensors using only 5 pins, optimizing your system's efficiency. - Easily control the board by connecting 4 digital outputs to the address selection pins (S0-S3) of the chip. Send the binary address of the desired channel as specified in the data sheet. This straightforward setup simplifies sensor integration. - The board's capability to handle digital signals enables the transmission of serial data over TTL to multiple devices. For example, you can connect the Tx pins of 16 devices to a single Rx pin on a microcontroller, allowing you to select one device for communication at a time. - The CD74HC4067 functions like a rotary switch, internally routing a common pin (Com) to one of the 16 channel pins (Chanxx), ensuring reliable signal routing without the need for complex wiring. - For bi-directional communication, simply add a second board to connect the Tx line of the microcontroller to the Rx lines of the 16 devices. This flexibility allows for similar setups with protocols like I2C and SPI, enhancing your project’s capabilities. - Ideal for applications in robotics, sensor networks, and data acquisition systems, the CD74HC4067 simplifies the design of complex electronic systems while saving space and reducing wiring clutter. Its compact design and robust performance make it an essential component for your next project.
