Design a Custom BoardAbout This Component
Single-pole double-throw analog switch for 1.65V to 5.5V operation with approximately 6Ω on-state resistance and 0.5ns switching speed. Handles both analog and digital signals with rail-to-rail capability and operates to 125°C. Ideal for signal routing, multiplexing, and bus switching in portable and IoT 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.
