  • This is a breakout board for the very handy 16-Channel Analog/Digital Multiplexer/Demultiplexer CD74HC4067.

  • This chip is like a rotary switch - it internally routes the common pin

  • (COM in the schematic, SIG on the board)to one of 16 channel pins (CHANxx).

  • It works with both digital and analog signals (the voltage can’t be higher than VCC),

  • and the connections function in either direction.

  • To control it, connect 4 digital outputs to the chip’s address select pins (S0-S3),

  • and send it the binary address of the channel you want (see the datasheet for details).

This allows you to connect up to 16 sensors to your system using only 5 pins!

  • Since the mux/demux also works with digital signals,

  • you can use it to pipe TTL-level serial data to or from multiple devices.

  • For example, you could use it to connect the TX pins of 16 devices to one RX pin on your microcontroller.

  • You can then select any one of those 16 devices to listen to.

  • If you want two-way communications, you can add a second board to route

  • your microcontroller’s TX line to 16 device’s RX lines.

  • By using multiple boards, you can create similar arrangements for I2C, SPI, etc.

  • The internal switches are bidirectional, support voltages between ground and VCC,

  • have low “on” resistance and low “off” leakage, and to prevent crosstalk, perform “break-before-make” switching.

  • The board also breaks out the chip’s “enable” pin, which when driven high,

  • will completely disconnect the common pin (all switches “off”).


  • 2V to 6V operation

  • “On” resistance: 70 Ohms @ 4.5V

  • 6ns break-before-make @ 4.5V

  • Wide operating temperature range: -55C to 125C
