Description
This handy breakout board features the CD74HC4067, a versatile 16-channel analogue/digital multiplexer and demultiplexer.
Acting like a rotary switch, it routes a single common pin (COM/SIG) to one of 16 channel pins (C0–C15), allowing easy expansion of analog or digital inputs and outputs with minimal microcontroller pins.
Compatible with both analogue and digital signals (up to VCC voltage), this board enables you to connect up to 16 sensors or devices using just 5 control pins.
Perfect for projects requiring signal multiplexing, sensor arrays, or serial data routing.
- Function: Multiplex up to 16 analogue/digital channels to one common output
- Operating Voltage: 2V to 6V
- Low “On” Resistance: 70Ω @ 4.5V for minimal signal loss
- Break-Before-Make Switching: 6ns delay at 4.5V prevents crosstalk
- Channel Control Pins: S0 to S3 for binary channel selection
- Enable Pin Breakout: Allows disabling all channels by driving high
- Analog Signal Inputs: C0–C15 (16 channels)
- Analog Signal Output: SIG (common pin)
- Operating Temperature: -55°C to 125°C
- Module Size: Approx. 4cm x 1.8cm (1.57″ x 0.7″)
- Bidirectional switches suitable for multiplexing signals both ways
What’s Included:
