Overview
The FSUSB42UMX, produced by onsemi, is a low-power, two-port, high-speed USB2.0 switch. This device is configured as a double-pole, double-throw (DPDT) switch, optimized for switching between high-speed (480 Mbps) or Full-Speed (12 Mbps) sources. It is compatible with the requirements of USB2.0 and features an extremely low on capacitance (CON) of 3.7 pF, which minimizes signal distortion. The FSUSB42UMX is designed to operate with minimal current consumption, making it suitable for ultra-portable applications.
