## Description

The Texas Instruments CD74HC4067 is a 16-channel analogue multiplexer/demultiplexer IC. It allows you to route one of 16 analogue signals to a single common pin (or vice versa) using just 4 digital control lines plus an enable pin — effectively expanding a single ADC channel to read from 16 sources. This is the bare IC in a 24-pin SSOP package. A 28-pin SSOP-to-DIP adapter board is recommended for breadboard prototyping. Key Features 16 Channels – Select any of 16 analogue inputs/outputs with 4 digital control pins Bidirectional – Works as both multiplexer and demultiplexer Low On-Resistance – Suitable for analogue signal routing Wide Voltage Range – 2V to 6V operating voltage 24-Pin SSOP Package – Compact surface-mount form factor Specifications Part Number – CD74HC4067 Channels – 16 Package – 24-pin SSOP Operating Voltage – 2V to 6V Manufacturer – Texas Instruments Ideal For Expanding ADC inputs on Arduino and other microcontrollers Analogue signal routing and switching Sensor arrays requiring multiplexed readings Package Contents 1× CD74HC4067 16-channel multiplexer IC (SSOP-24) Resources Datasheet (PDF)
