Design a Custom BoardAbout This Component
Dual bidirectional voltage-level translator for I2C, SMBus, and I3C applications supporting mixed-voltage domains from 0.9V to 5V. Provides seamless translation between VREF1 (0.9-3.3V) and VREF2 (1.8-5.5V) with low ON-state resistance and no direction pin required. Features enable control for bus isolation, 5V tolerance, and lockup-free operation in 8-pin VSSOP package.
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.
