Design a Custom BoardAbout This Component
Bidirectional voltage-level translator for I2C and SMBus interfaces. Enables communication between devices operating at different logic voltages (e.g., 3.3V to 5V). Integrates dual channels with integrated pull-up resistors, supporting hot-insertion capability and low power consumption. Ideal for mixed-voltage digital 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.
