Design a Custom BoardAbout This Component
8-channel analog multiplexer/demultiplexer in 16-pin TSSOP package. Features 240Ω switch resistance, single supply operation (3V to 18V), and high input impedance. Ideal for signal routing, audio switching, and data acquisition systems where space is critical.
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.
