Best Digital Multiplexers

Best Choice No. 1
ACEIRMC 10pcs CD74HC4067 16-Channel Analog Digital Multiplexer Breakout Board Module for Arduino 2V-6V Microcontroller 16 Device RX Lines
  • 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.
  • Analog output: DIG;Channel control: S0-S3
  • This is a breakout board for the very handy 16-Channel Analog/Digital Multiplexer/Demultiplexer CD74HC4067.
  • 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. This allows you to connect up to 16 sensors to your system using only 5 pins!

Andifany 10Pcs 16CH Analogue Multiplexer Module 74HC4067 CD74HC4067 Precise Module Digital Multiplexer MUX Breakout Board
  • Because the multiplexer can also process digital signals, you can use it to transfer TTL-level serial data to multiple devices through pipe or transfer from multiple devices.
  • Drive it to a high level, and it will completely disconnect the common pins (all switches are disconnected).
  • It is suitable for digital and analog signals (voltage cannot be higher than VCC) and can be connected in either direction. To control this, please connect the four digital outputs to the address selection pin of the chip (SO-S3) and send it the binary address of the desired channel.
  • This is a very convenient 16 channel CD74HC4067 analog/digital multiplexer/demultiplexer.
  • The internal switch is bidirectional, with a low on resistance and off leakage, and to prevent cross talk, please turn off the switch first and then on.
Best Choice No. 5
Ximimark 2Pcs 16CH Analog Digital Multiplexer Breakout Board Module CD74HC4067 CMOS Precise Module for Arduino
  • 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).

  • 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. 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”).
