Design a Custom BoardAbout This Component
Dual bidirectional I2C/SMBus voltage-level translator for mixed-mode applications. Translates between 1.2V to 5V rails without requiring a direction pin, with <1.5ns propagation delay and 3.5Ω ON-resistance. Includes enable control for bus isolation and lockup-free operation, suitable for servers, routers, and industrial systems.
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.
