16-Channel Analog/Digital Multiplexer MUX CD74HC4067

This module with the CD74HC4067 multiplexer expands an analogue input or output of an Arduino to 16 channels. Switching requires four digital outputs, plus one analogue pin for the common signal. The multiplexer passes analogue and digital signals in both directions.

Recommended Accessories:

• Pin header male 1 X 40 pole RM 2.54mm straight short pin
• Dupont Jumper Cable Set 10cm 60 pieces.

Features:

• 16 channels C0 to C15, one at a time connected to SIG
• Binary channel selection via S0 to S3
• EN at HIGH disconnects all channels from SIG
• Signal voltage must stay between GND and VCC
• Solder pads without pin header, 2 mounting holes

Application Examples:

• Many potentiometers or sensors on one analogue input
• Many buttons on few pins
• Switching digital signals
