Design a Custom BoardAbout This Component
Single-channel bidirectional voltage-level translator for translating logic signals between different voltage domains. Features configurable direction control with auto-sensing capability, operating from 1.65V to 5.5V on each channel. Ideal for interfacing between 3.3V and 5V logic systems, I2C/SPI buses, and mixed-voltage applications.
Package: SOT-363 · 6 pins
Why does this need a breakout?
The SOT-563's 1.27mm pin pitch and small footprint make hand-soldering difficult and breadboard prototyping impossible. A breakout board brings these pins to standard 0.1" spacing, enabling quick breadboard integration for dual transistors, level shifters, and compact buck converters without requiring SMD soldering skills or microscopy.
