- Versatile Signal Processing: This 16-channel analog/digital multiplex/demultiplex breakout board (CD74HC4067) efficiently handles both digital and analog signals, allowing for flexible applications. It can process signals without exceeding VCC and supports directional connectivity. - Easy Control Setup: Connect four digital outputs to the address selection pins (S0-S3) of the chip to select the desired channel by sending the binary address. This setup enables you to connect up to 16 sensors using just five pins. - Streamlined Data Transmission: The Mux/Demux capability allows for the transmission of serial data in TTL format to multiple devices. For example, you can connect the Tx pins of 16 devices to a single Rx pin on a microcontroller, facilitating easy channel selection. - Efficient Routing: The CD74HC4067 chip functions similarly to a rotary switch, routing a common pin (Com) to one of the 16 channel pins (Chanxx) seamlessly. - Bi-Directional Communication: For applications requiring bi-directional communication, you can add a second board to direct the Tx line from the microcontroller to the Rx lines of the 16 devices. This setup allows for expanded configurations for protocols like I2C and SPI. Use Scenarios: 1. Sensor Networks: Connect multiple sensors to a microcontroller for comprehensive data collection in environmental monitoring systems. 2. Communication Systems: Simplify communication networks by routing multiple device outputs through a single microcontroller input, enhancing system efficiency. 3. Prototyping: Ideal for engineers and developers creating prototypes that require multiple inputs and outputs without complex wiring.
