CD74HC4067 16-Channel Analog/Digital Multiplexer Breakout — Pack of 2 What it is - A ready-to-use breakout board built around the CD74HC4067 16-channel analog/digital multiplexer. Each module lets you select one input from 16 signals under digital control. Why you need it - Expand limited inputs: read up to 16 sensors or signal lines using a single ADC or input pin on your microcontroller. - Reduce wiring and complexity: route many analog or digital signals through one controlled interface instead of running multiple long traces or cables. - Speed up development: the breakout form factor simplifies prototyping and integration on breadboards and custom PCBs. Key benefits and attributes - Function: Selects one of 16 analog or digital channels using digital address lines for efficient multiplexing. - Compatibility: Works with standard analog and digital circuits and common microcontrollers for prototyping and embedded systems. - Size and form: Compact breakout board design provides easy access to signals for quick wiring and testing. - Performance: Provides a straightforward method to switch and measure multiple signals without redesigning hardware. - Pack of 2: Two identical modules included, convenient for projects that need multiple multiplexers or spares. How it solves problems - Conserves ADC/DIO resources by enabling many sensors to share a single input. - Simplifies PCB layout and reduces connectorization when gathering multiple signal channels. - Makes iterative testing faster by providing an off-the-shelf board rather than assembling discrete components. Practical applications (examples) - Sensor arrays: Monitor up to 16 temperature, light, or environmental sensors with one ADC input on an Arduino or similar controller. - Data acquisition and prototyping: Rapidly switch between multiple signal sources for testing measurement circuits or validating designs. - Signal routing and audio switching: Route or monitor multiple analog signal paths in small-scale audio, robotics, or instrumentation projects. What to expect in use - Control the selected channel with simple digital address lines; use the board to feed the chosen signal to your ADC or processing stage. - Integrates into breadboard and prototype environments to accelerate development without changing your primary controller design. Includes - Two CD74HC4067 16-channel analog/digital multiplexer breakout modules.
