2010. 2. 10 1/10 semiconductor technical data revision no : 0 high-speed(480mbps) usb2.0 dpdt switch description the KUSB50QN is a high-speed(480mbps) usb2.0 signal switch. configured as a double-pole double-throw (dpdt) switch, it is optimized for switching between 2 hi-speed sources or a hi-speed(480mbps) and full-speed(12mbps) source. its wide bandwidth (720mhz) is wide enough to pass high-speed usb2.0 differential signals. industry-leading advantages include a propagation delay of less than 250ps, resulting from its low channel resistance and low on capacitance. it is bidirectional and offers little or no attenuation of the high-speed signal at the outputs. its high channel-to-channel crosstalk rejection results in minimal noise interference. the switch is designed to minimize current consumption even when the control voltage applied to the s pin, is lower than the v cc . the KUSB50QN also offers over-voltage protection per the usb2.0 specification. with the chip powered on or off, all data i/o pins can withstand a short to vbus(5.25v). features ? usb2.0 compliant (high-speed and full-speed). ? low on resistance, 5.5 ?
