Overview

The CD74HC4067PWR is a high-speed CMOS 16-channel analog multiplexer and demultiplexer designed for 2V to 6V operation. It utilizes four digital select inputs to connect one of sixteen bidirectional inputs/outputs to a common output, featuring an active-low Enable pin to disable all channels. This part is ideal for expanding the I/O capabilities of microcontrollers by allowing a single analog or digital pin to interface with 16 different signal lines.

Why Choose This Part

The IC features a wide operating temperature range of -55C to 125C and a high -3db bandwidth of 89MHz, making it suitable for both slow sensor data and faster signal switching. Its break-before-make internal switching prevents signal overlap and shorting between channels during transitions. With a maximum on-state resistance of 160 Ohms at 5V and low CMOS power consumption, it provides an efficient way to multiplex signals without significant signal degradation.

Applications

Analog Signal Gating
Routing multiple sensor signals to a single Analog-to-Digital Converter (ADC) input to reduce system pin count.
Digital Control of Gain
Switching different resistor values into an op-amp feedback loop to adjust signal amplification dynamically.
Squelch and Signal Muting
Inhibiting signal paths in audio or communication equipment using the global enable control.
Data Communication Routing
Directing digital serial data streams from one source to one of sixteen different destinations in a demultiplexer configuration.

Getting Started

To use this part, connect the four select pins (S0-S3) to your microcontroller GPIO to address channels 0-15. Ensure the Enable (E) pin is pulled low to activate the switch, or high to put all channels in a high-impedance state. For prototyping, this TSSOP-24 package is commonly found on breakout boards that adapt the 0.65mm pin pitch to standard 0.1-inch breadboard headers.
