CD74HC4067 Analogue Digital Multiplexer Module

CD74HC4067 Analog Digital Multiplexer Breakout 16 Channel Multiplexer

The CD74HC4067 multiplexer breakout board is a versatile solution for expanding I/O capabilities in projects, especially with microcontrollers like Arduino. Here are its key features and specifications:

Key Features:

1. 16-Channel Multiplexer: Routes one common pin to one of 16 channel pins, functioning like a rotary switch.
2. Analog and Digital Compatibility: Handles both types of signals, with bidirectional functionality.
3. Control with 5 Pins: Connects to four digital outputs for address selection, plus one enable pin.
4. Versatile Signal Routing: Can route TTL-level serial data, I2C, SPI, and other signals.
5. Low On-Resistance and Leakage: Ensures minimal signal loss and interference.
6. Break-Before-Make Switching: Prevents crosstalk by ensuring one connection is broken before another is made.
7. Enable Pin: When driven high, it disconnects the common pin from all channels.

Specifications:

• Voltage Range: Supports voltages between ground and VCC.
• Size: Compact breakout board form factor.
• Control Interface: 4 address pins (digital outputs) plus enable pin.

Applications:

• Sensor Control: Ideal for projects needing multiple sensor inputs with limited microcontroller pins.
• Signal Multiplexing: Useful for managing multiple digital or analog signals in a compact design.
• Serial Data Routing: Can direct TTL-level serial data among various devices.

This multiplexer breakout board simplifies the control of multiple sensors or signals with minimal microcontroller I/O pins, making it a valuable addition to any electronics toolkit.
