- The Mux/Demux supports both digital and analog signals, making it ideal for transferring TTL-level serial data to multiple devices. It allows for seamless connections, such as linking 16 transmit (Tx) devices to a microcontroller's receive (Rx) pin, enabling the selection of any of the 16 hearing aids. - For bi-directional communication, simply add a second board to connect the microcontroller's Tx line to 16 Rx devices. This flexibility allows you to create similar circuits for various protocols, including I2C, SPI, and others. - The device accommodates both digital and analog signals (voltage must not exceed VCC) and can be connected in any direction. Control is straightforward: connect four digital outputs to the chip address selection pins (S0-S3) and send a binary address for the desired channel. This setup supports up to 16 sensors using a 5-pin configuration. - The CD74HC4067 is a reliable 16-channel multiplexing/demultiplexing solution. It functions like a rotary switch, directing the common contact (labeled Com) to one of the 16 channel contacts (Chanxx) with ease. Key Benefits: - Simplifies connections for multiple devices, enhancing system efficiency. - Supports various protocols, offering versatility for different applications. - Easy to control with a simple binary addressing system. Use Scenarios: 1. Connect multiple hearing aids to a single microcontroller for streamlined audio processing. 2. Create sensor networks by connecting up to 16 sensors, optimizing data collection in environmental monitoring. 3. Develop complex communication systems by integrating with I2C or SPI for expandable projects. Specifications: - Compatibility: Works with both digital and analog signals. - Size: Compact design for easy integration into various projects. - Performance: Reliable operation for multiple channels without degradation of signal quality.
