4067 IC 16-Channel Analog Demultiplexer
The CD4067BE is a high-performance 16-channel analog multiplexer/demultiplexer designed to route one of 16 analog or digital signals to a common output line. Engineers use this IC to simplify circuit complexity when handling multiple signals, as it allows for the selection of one channel from sixteen using only four control lines.
This IC supports both analog and digital signals and operates over a wide voltage range, making it ideal for interfacing with microcontrollers, ADCs, DACs, and other signal processing components. Each of the 16 channels features low “on” resistance and minimal crosstalk, ensuring high signal integrity.
