Product Description


    16 channel analog multiplexer, perfect for Arduino or Raspbarry Pi



    •  Breakout board for the 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),
    •   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”).
