The MUX 16-Channel Analog Multiplexer 74HC4067 Blue module is a breakout board that includes the CD74HC4067, a16-channel Analog/Digital Multiplexer/Demultiplexer IC. Engineered to effortlessly link up to 16 analog sources or sensors to a microcontroller with just five pins, it optimizes connectivity efficiency. The IC requires 4 digital pins and 1 analog-to-digital conversion pin, showcasing bidirectional functionality for distributing a single serial stream to multiple outputs. Its adaptability extends to digital signals like serial, I2C, and SPI, offering the capability to connect numerous serial devices to a microcontroller's RX pin. Operating within a broad voltage range, the IC features bidirectional switches with a "Break-Before-Make" switching time of 6ns at 4.5V, ensuring efficient and reliable signal transitions. Low "on" resistances and minimal "off" leakages contribute to the effectiveness of signal switching, and an enable control allows for the deactivation of all switches.
