Design a Custom BoardAbout This Component
Dual-channel bidirectional voltage-level translator for interfacing 3.3V and 5V logic circuits. Enables communication between low and high voltage domains with minimal propagation delay. Commonly used in microcontroller interfaces, sensor circuits, and mixed-voltage applications requiring level shifting on I2C, SPI, or general-purpose digital signals.
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.
