CD74HC4067 16 Channel Analog Multiplexer Price in Bangladesh

The CD74HC4067 16 Channel Analog Multiplexer is a versatile CMOS-based analog switch designed to expand the input and output capabilities of microcontrollers such as Arduino, ESP32, ESP8266, STM32, Raspberry Pi (with ADC), and other embedded development platforms. It allows a single analog or digital input/output pin to communicate with 16 separate channels, making it an excellent solution for projects requiring multiple sensors or signal sources while using very few GPIO pins.

Modern embedded systems often face limitations in the number of available analog input pins. For example, Arduino Uno provides only six analog inputs, while many applications require monitoring numerous sensors simultaneously. The CD74HC4067 solves this limitation by functioning as a 16-to-1 analog multiplexer, enabling one common signal pin to be connected to any one of sixteen independent channels under the control of only four digital address lines.

The device supports both analog and digital signals, making it suitable for reading analog sensors, controlling digital switches, routing communication signals, selecting audio channels, multiplexing voltage measurements, and numerous other switching applications. It features low ON resistance, high switching speed, break-before-make switching, and low power consumption, ensuring reliable signal transmission with minimal distortion.

The module uses four selection pins (S0, S1, S2, and S3) to choose one of the sixteen available channels. An additional Enable (EN) pin allows users to disconnect all channels when required. This simple addressing method makes software implementation straightforward while significantly reducing the number of microcontroller pins needed.

The CD74HC4067 is widely used in robotics, IoT systems, automation, environmental monitoring, sensor networks, laboratory instruments, industrial data acquisition, and educational electronics projects. It is particularly useful when multiple analog sensors such as LDRs, potentiometers, pH sensors, gas sensors, moisture sensors, and temperature sensors need to be connected to a single ADC input.

In addition to sensor expansion, the module is also employed in audio routing, communication signal switching, measurement systems, multiplexed keyboards, touch sensing applications, battery monitoring systems, and signal acquisition devices. Because it supports bidirectional analog switching, the module can function as either a multiplexer or a demultiplexer depending on the application.

With its compact PCB design, low power consumption, and excellent compatibility with popular development boards, the CD74HC4067 has become one of the most widely used expansion modules in the maker and embedded systems community.

🔍 What is a 16 Channel Analog Multiplexer?

A 16 channel analog multiplexer is an electronic switching device that connects one common signal line to one of sixteen input/output channels.

Instead of requiring sixteen separate analog input pins, a microcontroller can read sixteen sensors using only:

• Four address pins (S0–S3)
• One signal pin
• One optional Enable pin

This significantly expands the number of sensors or signals that can be connected without increasing hardware complexity.

⚡ Working Principle of CD74HC4067 16 Channel Analog Multiplexer

The CD74HC4067 operates as an electronically controlled switch.

Using four digital selection inputs (S0–S3), the microcontroller selects one of the sixteen available channels. Once selected, that channel is electrically connected to the common SIG pin, allowing the microcontroller to read or transmit the signal.

For example, if sixteen potentiometers are connected to channels C0–C15, the Arduino simply changes the address pins to select each channel one at a time and reads the analog voltage through a single analog input pin.

The built-in break-before-make feature ensures that one channel disconnects before another connects, reducing switching errors and preventing short circuits between channels.
