Design a Custom BoardAbout This Component
Bidirectional DPDT USB 2.0 switch IC for multiplexing high-speed (480 Mbps) or full-speed (12 Mbps) sources. Features 3.7 pF on-capacitance, 3.9 Ω on-resistance, >720 MHz bandwidth, and ultra-low 1 μA maximum power consumption. Ideal for portable devices requiring USB port sharing in cell phones, PDAs, cameras, and notebooks.
Package: MSOP-10 (P0.5mm) · 10 pins
Why does this need a breakout?
The 0.5mm pin pitch makes hand soldering impractical without specialized equipment, and the tiny 3x3mm footprint cannot connect directly to breadboards. A breakout board brings these pins to standard 0.1-inch spacing, enabling rapid prototyping of analog-to-digital converters, boost controllers, and audio switches without reflow soldering or custom PCBs.
