Available: Out of Stock

This is a breakout board featuring the 74HC4067, a 16-channel analog multiplexer/demultiplexer capable of routing both analog and digital signals in either direction. It allows one of 16 input channels to be connected to a single output, or conversely, one input can connect to any of the 16 output channels. This component can handle analog signals, such as those from analog sensors or a group of potentiometers, as well as digital signals from switches, digital sensors, or even for serial communication. The 74HC4067 operates within a voltage range of 2 to 6V, making it compatible with both 3.3V and 5V logic levels.

Four address lines (S0-S3) are used to select one of the 16 channels, linking it to the input/output pin (SIG). The addressing is binary; for instance, address 0000 corresponds to Channel 0, while address 1111 refers to Channel 15. When a channel is activated, it has an approximate resistance of 70 ohms, allowing signals to pass in both directions. With a 5V power supply, we measured around 60 ohms. The maximum current through any channel is 25mA.

The board includes an enable pin (EN) that is active LOW and defaults to this state. When set to LOW, the device activates the channel selected by the address lines; if EN is pulled HIGH, all channels are disabled.

The electronics module features two rows of header solder points for wire or header pin connections, depending on the application. The pin configuration is as follows:

1×8 Header Location:-

  • SIG: Signal Input/Output, typically connected to an analog input or digital I/O on the microcontroller.
  • S3: Binary Address Bit 3; connects to one of the four digital output pins on the microcontroller to select the channel.
  • S2: Binary Address Bit 2.
  • S1: Binary Address Bit 1.
  • S0: Binary Address Bit 0.
  • EN: Enable, internally pulled LOW by default to enable channels; can be pulled HIGH to disable all channels.
  • VCC: 2 to 6V, usually connected to 5V or 3.3V to match the microcontroller's power.
  • GND: Ground, must be shared with the microcontroller.

1×16 Header Location:-

  • C15: Channel 15.
  • C0: Channel 0.
