How many control pins are required to operate the CD74HC4067 module?

The module requires only 4 digital control pins (S0, S1, S2, S3) from your microcontroller to select and communicate with any of the 16 channels. An additional EN pin is used to enable or disable the module.

Can this module handle both analog and digital signals?

Yes, the CD74HC4067 supports both analog and digital signals. It can route analog inputs like temperature sensors, potentiometers, and light sensors as well as digital inputs like buttons and switches to your microcontroller's ADC or GPIO pins.

What is the operating voltage range of this multiplexer module?

The CD74HC4067 module typically operates at 2V to 6V DC, making it compatible with both 3.3V logic controllers like ESP32 and Raspberry Pi, and 5V logic boards like Arduino Uno.

Is this module compatible with Raspberry Pi and ESP32, or only Arduino?

The module is compatible with Arduino, ESP32, Raspberry Pi, STM32, and most other microcontroller platforms. It communicates via standard digital GPIO pins, so any development board with at least 4 available digital pins can control it.

What is the maximum signal frequency the CD74HC4067 can handle?

The CD74HC4067 can typically handle signal frequencies up to several MHz depending on the operating voltage. At 4.5V supply, the propagation delay is around 10-15 nanoseconds, making it suitable for most sensor and switching applications in DIY electronics projects.
