The onsemi FSUSB42MUX is a low-power, bidirectional, two-port high-speed USB 2.0 analog switch configured as a double-pole, double-throw (DPDT) switch. It is optimized for switching between two USB High-Speed or Full-Speed sources and supports data rates up to 480Mbps, making it suitable for USB port sharing and high-speed differential signal routing.
The FSUSB42 features low parasitic capacitance and resistance, with a typical ON capacitance of 3.7pF and typical ON resistance of 3.9Ω at VCC = 3.0V. Its wide 720MHz -3dB bandwidth helps preserve USB signal integrity with minimal edge and phase distortion, while strong channel-to-channel isolation reduces interference.
The device operates from a recommended 2.4V to 4.4V supply and draws only 1μA maximum quiescent current, making it suitable for portable and battery-powered systems. Its USB switch I/O pins also tolerate overvoltage up to 5.25V when VCC is 0V, reducing the need for additional external protection components.
The FSUSB42MUX orderable version is supplied in a 10-lead MSOP package. onsemi lists it as an active product with tape-and-reel packaging of 4,000 units per reel and an operating temperature range of -40°C to +85°C. Typical applications include mobile devices, storage peripherals, digital cameras, notebooks, displays, TVs and set-top boxes.
