Design a Custom BoardAbout This Component
Single-channel I2C redriver IC in 8-VSSOP package designed to extend I2C bus range and improve signal integrity over long traces or heavily loaded buses. Regenerates I2C clock and data signals to restore voltage levels and timing margins. Commonly used in systems requiring robust I2C communication across multiple PCB segments or when driving multiple slave devices with capacitive loading.
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.
