Design a Custom BoardAbout This Component
Single 8-channel analog multiplexer/demultiplexer IC implementing an SP8T solid-state switch with digitally-controlled channel selection. Features low ON impedance (~280Ω), very low OFF leakage current, and operates across 3.0–18V supply range with analog signal handling up to full supply voltage. Ideal for audio/video signal routing, sensor multiplexing, and instrumentation applications requiring low-noise analog switching.
Package: SOIC-16 (3.9×9.9mm) · 16 pins
Why does this need a breakout?
The 1.27mm pin pitch on this 16-pin package makes hand-soldering impractical and breadboard mounting impossible. A breakout board brings the pins to standard 2.54mm spacing, enabling quick prototyping of RS-232/RS-485 transceivers, ADCs, and line drivers without requiring surface-mount soldering skills or PCB fabrication.
