Design a Custom BoardAbout This Component
Bidirectional voltage-level translator for translating signals between different logic voltage domains. Supports simultaneous two-way communication on up to 4 channels with minimal propagation delay. Ideal for interfacing 3.3V and 5V logic systems, I2C/SPI bus bridging, and mixed-voltage designs where level shifting is required without direction control pins.
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.
