Design a Custom BoardAbout This Component
CMOS analog multiplexer/demultiplexer with 8 independent channels and common output. Features 240 ohm on-resistance, wide supply range (3-18V), and low power consumption typical of CD4000-series logic. Suitable for audio/video switching, signal conditioning, data acquisition, and analog signal routing applications.
Package: TSSOP-16 (4.4×5mm) · 16 pins
Why does this need a breakout?
The 0.65mm pitch makes hand soldering difficult and error-prone; a breakout board lets you solder standard headers instead. This package hosts precision analog and mixed-signal ICs like DACs and ADCs that benefit from clean PCB layouts and decoupling placement. Prototyping becomes faster with breadboard-compatible pin headers, eliminating the need for a custom carrier PCB.
