Design a Custom BoardAbout This Component
Dual single-pole single-throw analog switch in 8-VSSOP package with low ON resistance (21Ω at 9V typical) and enable control. Operates from 2.0V to 10.0V supply with automotive AEC-Q100 Grade 1 qualification. Suitable for signal routing and multiplexing in automotive and industrial applications.
Package: MSOP-8 · 8 pins
Why does this need a breakout?
The 0.65mm pitch and tiny 3×3mm form factor make hand soldering challenging and impractical for breadboard prototyping. A breakout board converts this compact SMD package into a standard header layout, enabling reliable connections and rapid iteration without specialized soldering equipment or rework risk.
