4052 (Dual 4-Channel Multiplexer/Demultiplexer)

Overview

The 4052 is a versatile dual 4-channel analog multiplexer/demultiplexer integrated circuit (IC) from the 4000-series CMOS family. It allows you to route one of four input signals to a common output (multiplexer) or distribute a single input signal to one of four outputs (demultiplexer). This bidirectional capability makes it an essential building block for signal routing, data acquisition, and analog switching in a wide range of electronic projects.

Key Features

• Dual 4-channel configuration: Two independent multiplexer/demultiplexer circuits in a single package.
• Bidirectional operation: Can be used as a multiplexer or demultiplexer.
• Wide analog input voltage range: Handles signals from -5V to +5V (with Vee connected to -5V) or 0V to +10V (single supply).
• Low ON resistance: Typically 80 ohms, ensuring minimal signal attenuation.
• Low power consumption: CMOS technology ensures very low quiescent current.
• Break-before-make switching: Prevents momentary shorting between channels.
• Wide operating voltage range: Works from 3V to 20V.
• Standard 16-pin DIP package: Easy to use on breadboards and PCBs.

Applications & Use Cases

• Analog signal multiplexing: Select between multiple sensor inputs for a single ADC channel.
• Data acquisition systems: Expand the number of analog inputs on microcontrollers like Arduino, ESP32, or Raspberry Pi.
• Audio/video switching: Route audio signals in mixers or video signals in CCTV systems.
• Digital signal routing: Switch digital logic lines in test equipment or communication systems.
• Sample-and-hold circuits: Use as a front-end switch for precision analog circuits.
• Programmable gain amplifiers: Switch different feedback resistors to change gain.
