CD4067 16-Channel Analog Multiplexer/Demultiplexer – High-Voltage CMOS Signal Switch 24-Pin DIP

The CD4067 is a highly integrated CMOS 16-channel analog multiplexer/demultiplexer designed for digitally controlling the routing of analog or digital signals. It acts like a 16-position mechanical switch that is controlled electronically by a 4-bit binary address. Whether you need to read 16 different sensors using only one analog pin on a microcontroller or route one signal to 16 different destinations, the CD4067 is the professional solution. Unlike purely digital switches, the CD4067 is bidirectional and can handle analog voltages, making it perfect for audio routing, data acquisition systems, and analog signal level monitoring. Its ability to operate at voltages up to 18V allows it to interface directly with higher-voltage industrial sensors that standard 5V logic chips cannot handle. The 24-pin DIP through-hole package provides excellent mechanical stability and is easy to integrate into prototyping boards or industrial control PCBs. Whether you are building an automated testing rig, a multichannel audio mixer, or an environmental monitoring system with dozens of sensors, the CD4067 offers a reliable, space-saving, and highly flexible signal management platform.

Key Features:

Wide Analog Signal Range Capable of switching signals with amplitudes up to the full supply voltage (VDD to VSS).

Low "On" Resistance Typically 125 Ohms at 15V, ensuring minimal signal attenuation and distortion during transmission.

Inhibit Control Input Features a dedicated Inhibit pin that, when high, turns all channels off, allowing for easy expansion and bus-sharing.

High Voltage CMOS Operation Supports a wide supply voltage range from 3V to 18V, making it compatible with various logic levels and industrial systems.

Low Crosstalk and Leakage Engineered for high isolation between channels, preventing signal bleed in sensitive precision circuits.
