CD74HC4067 16 Channel Analog Digital Multiplexer MUX Breakout Board Module US

$7.49

CD74HC4067 16-Channel Multiplexer -- connect 16 analog or digital sensors to Arduino using only 5 pins. Acts like a rotary switch routing a common SIG pin to any of 16 channels (C0-C15) via 4-bit address pins S0-S3. offerirectional. Analog & digital.

ADDRESSING: Set S3-S2-S1-S0 in binary to select a channel. Channel number = binary address. Example: C9 = S3:1, S2:0, S1:0, S0:1.

IMPORTANT: Signal voltage must NOT exceed VCC -- can permanently damage chip. Keep EN pin LOW (tie to GND) to enable. Add 10µs settling delay before reading SIG after channel switch.

CD74HC4067 16-Channel Analog/Digital Multiplexer Breakout Board -- 16 Sensors, 5 Pins

The CD74HC4067 breakout board solves one of the most common problems in Arduino projects: running out of input pins. It works like an electronically controlled rotary switch, routing a single common signal pin (SIG) to any one of 16 channel pins (C0–C15) -- letting you connect up to 16 sensors or devices while using only 5 microcontroller pins. It handles both analog and digital signals, works in both directions, and operates from 2V to 6V.

⭐ Key Features

16 Channels, 5 Pins: S0, S1, S2, S3 (address) + SIG (signal) -- that\'s all you need to control 16 independent channels.
Analog & Digital: Works with analog voltages and digital logic signals on the same board.
offerirectional: Use as a multiplexer (many inputs → one output) or demultiplexer (one input → many outputs).
Enable Pin (EN): Drive EN HIGH to disconnect SIG from all channels simultaneously -- ideal for power saving or bus isolation.
Break-Before-Make Switching: Prevents channel-to-channel shorts during switching (6 ns at 4.5V).
Low On-Resistance: 70Ω at 4.5V -- clean signal switching with minimal voltage drop.
Wide Supply Voltage: 2V to 6V -- compatible with 3.3V and 5V systems.
Expandable: Cascade multiple boards using EN for board selection -- scale to 32, 48, or 64+ channels.

Set S0–S3 to the binary value of the channel you want to select. S0 is the least-significant bit. The channel number in decimal equals the binary address -- so channel 9 = S3:1, S2:0, S1:0, ⚠️ Important Notes⚠️ Signal voltage must not exceed VCC. Any voltage on C0–C15 or the SIG pin above VCC can permanently damage the chip. For 3.3V sensors on a 5V system, use a logic level converter on the signal lines.⚠️ EN pin must be held LOW to operate. Do not leave EN floating -- the chip may not enable reliably. Tie EN to GND for always-on operation, or drive it from a digital output pin for software control.💡 Add a settling delay. After switching channels, wait at least 10 microseconds before reading SIG to allow the signal to stabilize. In Arduino code: delayMicroseconds(10); after calling your channel-select function. 📦 What\'s in the Box
