This part is configured as a single pole, single-throw switch and is optimized for switching or iso- lating a high-speed (480Mbps) source or a high-speed and full-speed (12Mbps) source. The FSUSB31 is com- patible with the requirements of USB2.0 and features an extremely low on capacitance (CON) of 3.7pF. The wide bandwidth of this device (>720MHz) exceeds the band- width needed to pass the third harmonic, resulting in sig- nals with minimum edge and phase distortion. Superior channel-to-channel crosstalk minimizes interference. The FSUSB31 contains special circuitry on the D+ / D- pins that allows the device to withstand an over-voltage condition. This device is also designed to minimize cur- rent consumption even when the control voltage applied to the OE pin is lower than the supply voltage (VCC). This feature is especially valuable for ultra-portable applica- tions such as cell phones, allowing for direct interface with the general purpose I/Os of the baseband proces- sor. Other applications include port isolation and switch- ing in portable cell phones, PDAs, digital cameras, printers, and notebook computers. Ordering Information Pb-Free package per JEDEC J-STD-020B.
