Design a Custom BoardAbout This Component
Single-channel load switch with integrated 1-to-2 multiplexer in 8-SOIC package. Supports 5.5V operation with integrated protection including current limiting, thermal shutdown, and reverse current blocking. Ideal for power distribution in portable devices, USB applications, and systems requiring switchable power domains with minimal external components.
Package: SOIC-8 (3.9×4.9mm) · 8 pins
Why does this need a breakout?
An 8-pin SOIC with 1.27mm pitch is too fine for breadboards and hand-soldering without a microscope. A breakout board routes these pins to standard 0.1" headers, enabling rapid prototyping and reliable connections for op-amps, transceivers, and small power MOSFETs without requiring reflow equipment.
