FSUSB30 Low-Power 2-Port Hi-Speed USB 2.0 (480Mbps) Switch Features General Description Low On Capacitance, 3.7p F (typical) The FSUSB30 is a low-power, two-port, high-speed USB Low On Resistance, 6.5Ohm (typical) 2.0 switch. Configured as a double-pole double-throw Low power consumption (1µA maximum) (DPDT) switch, it is optimized for switching between two 10µA maximum ICCT over an expanded control high-speed (480Mbps) sources or a Hi-Speed and Full- voltage range (VIN = 2.6V, VCC = 4.3V) Speed (12Mbps) source. The FSUSB30 is compatible

Wide -3d B bandwidth, >720MHz with the requirements of USB2.0 and features an 8KV ESD protection extremely low on capacitance (CON) of 3.7p F. The wide Power-Off protection when VCC = 0V; D+/D- pins can bandwidth of this device (720MHz), exceeds the band- tolerate up to 5.25V width needed to pass the third harmonic, resulting in sig- Packaged in: nals with minimum edge and phase distortion.
