CD4052 Dual 4-Channel Multiplexer/Demultiplexer IC (DIP)

CD4052 Overview

The CD4052 Dual 4-Channel Multiplexer/Demultiplexer IC is a CMOS logic device that integrates two independent 4-channel analog multiplexers/demultiplexers into one through-hole DIP package. Each section routes one of four inputs to a common I/O pin under the control of binary address inputs, enabling compact and flexible signal routing for both analog and digital designs.

Key Features

• Two independent 4-channel analog multiplexers/demultiplexers in one IC.
• Wide supply voltage range: 3V to 15V.
• Low power consumption with high noise immunity.
• Low crosstalk between channels for clean signal switching.
• Compatible with analog and digital signals; handles voltages close to supply rails.
• Standard DIP package for easy breadboarding and prototyping.

Technical Specifications

• Multiplexer sections: 2 independent 4-channel switches.
• Control: Binary address inputs to select one of four channels per section.
• Supply voltage: 3V to 15V (single-supply operation supported).
• Signal type: Analog and digital (ensure signals remain within supply rails).
• Package: Through-hole DIP for easy prototyping and soldering.

Typical Applications

• Data acquisition and sensor multiplexing.
• Audio and video source switching.
• Communication and instrumentation circuits.
• Embedded systems and microcontroller I/O expansion.
• Test equipment and laboratory switching solutions.

Design and Usage Tips

Connecting and Controlling the CD4052

• Use binary address inputs to select channels; refer to the device datasheet for exact pin assignments and truth tables.
• Provide a clean VCC and GND; decoupling capacitors near the IC improve stability and noise performance.
• Keep all signal voltages within the supply rails to avoid latch-up or damage.
• If inputs may float, add pull-up or pull-down resistors to ensure defined states.

Analog Signal Considerations

• The CD4052 can pass analog signals near the rails, but performance (on-resistance and linearity) varies with supply voltage; test in your target supply conditions.
• For sensitive audio or precision analog paths, consider buffering the source or adding filtering to reduce switching transients.

Why Choose the CD4052 for Your Project

• Compact dual-channel configuration reduces board space and component count.
• Versatility to handle mixed-signal designs simplifies system architecture.
• Through-hole DIP makes it ideal for rapid prototyping and educational projects.
• Wide supply range enables compatibility with 3.3V and 5V microcontroller systems as well as higher-voltage designs.
