CD4051 Single 8-channel Multiplexer/Demultiplexer IC DIP-16 Package

The CD4051 is a single 8-channel analog multiplexer/demultiplexer IC in a DIP-16 package. It allows you to route one of eight input signals to a common output, or distribute a single input to one of eight outputs. This IC is essential for expanding the analog input or output capabilities of microcontrollers in sensor and signal routing projects.

Specifications

• Logic level: 3V to 15V (digital control signals)
• Analog signal range: 0V to VDD (full supply voltage)
• Interface: 3 digital select lines (A, B, C) and an inhibit pin
• Channel count: 8 channels (single-ended)
• Package: DIP-16
• On-resistance: typically 400 ohms at 10V supply

Compatible with

Arduino Uno, Arduino Nano, ESP32, ESP8266, Raspberry Pi (via GPIO), STM32, and any microcontroller with 3 digital output pins.

What you can build with it

• Multi-sensor data acquisition system – read up to 8 analog sensors using one ADC pin
• Audio signal routing – switch between multiple audio sources
• Test equipment – create a programmable signal selector for circuit testing
