Overview
The FSUSB42MUX by onsemi is a bi-directional, low-power, two-port, high-speed USB 2.0 switch. It is configured as a double-pole, double-throw (DPDT) switch, optimized for switching between any combination of high-speed (480 Mbps) or full-speed (12 Mbps) sources. This device is compatible with the requirements of USB 2.0 and features an extremely low on capacitance (CON) of 3.7 pF and a wide bandwidth of 720 MHz, ensuring signals with minimum edge and phase distortion. It is particularly suited for applications requiring efficient USB data and signal management, such as in cell phones, PDAs, digital cameras, notebooks, LCD monitors, TVs, and set-top boxes.
