The HW-178 74HC4067 module routes one of 16 analogue or digital channels through a shared SIG connection. Four binary select inputs choose the active channel, making it a practical way to expand Arduino, ESP32 and Raspberry Pi projects without using 16 separate signal pins.

What's in the box

HW-178 74HC4067 module

One assembled blue PCB with unsoldered through-holes. Pin headers are not included.

Great for

Reading several analogue sensors with one ADC input
Expanding data acquisition and test projects
Routing compatible digital or serial signals
Arduino, ESP32 and Raspberry Pi prototyping

Wiring & getting started

  1. Connect power

    Connect VCC to a 2V to 6V supply and connect GND to the controller ground.

  2. Connect signals

    Connect the shared signal to SIG, then connect each source or destination to C0 through C15.

  3. Select a channel

    Drive S0 to S3 with the channel's binary value. S0 is the least-significant bit, so 0000 selects C0 and 1111 selects C15.

  4. Set enable

    Hold EN low to enable the selected channel. Drive EN high to disconnect every channel.

Note: This module is a signal switch, not a voltage level shifter. Keep every switched signal between GND and the module VCC.

Frequently Asked Questions

Answers to the questions buyers ask most.

Can I use this with 3.3V boards such as ESP32?
Yes. Power the module from a compatible 3.3V supply and keep all switched signals between GND and VCC.
Does it work with analogue and digital signals?
Yes. The 74HC4067 switch is bidirectional and can route analogue or compatible digital signals within the module supply rails.
How is a channel selected?
Drive S0 to S3 with the binary number for C0 to C15. S0 is the least-significant bit and S3 is the most-significant bit.
Are pin headers included?
No. The assembled module is supplied with unsoldered through-holes and no pin headers.

Why Buy from NZN

Useful parts, fair prices and someone local to help.

I'm Lukas, an engineering student and maker based in Te Awamutu. NZN grew out of a CNC build that dragged on for months because every missing cable, bolt or electronic part meant another overseas order. I started the shop so Kiwi makers can spend more time building and less time waiting for the next parcel.
