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