Design a Custom BoardAbout This Component
High-speed 2-channel 2:1 analog switch supporting I3C and I2C protocols. Features 3 Ω on-resistance, 1.7 pF on-capacitance, and 3 GHz bandwidth for low-distortion signal routing. Includes power-off isolation and 1.8V/3.3V logic compatibility in compact 1.4×1.8 mm package, ideal for mobile and instrumentation applications.
Package: UQFN-10 (1.4×1.8mm) · 10 pins
Why does this need a breakout?
The 0.4mm pitch and sub-2mm body make hand soldering nearly impossible; a breakout board lets you work with standard 0.1" headers instead. The pads are hidden underneath, eliminating any breadboard prototyping path without this adapter. Essential for accessing analog switches, USB multiplexers, and microcontrollers in this compact package during development.
