WAS7223Q WAS7223Q USB High speed (480Mbps), DPDT Analog Switch Http//:www.willsemi.com Descriptions The WAS7223Q is a high performance, double pole double throw (DPDT) CMOS analog switch that operates from a single +2.3V to +4.5V power supply. The WAS7223Q is designed for switching of high-speed USB2.0 signals in handset and consumer applications, such as cell phones, digital cameras, and notebooks with hubs or controllers with limited USB I/Os. The WAS7223Q has low bit-to-bit skew and high channel-to-channel noise isolation, and is compatible with various standards, such as high-speed USB 2.0 (480Mbps). Each switch is bi-directional and offers little attenuation of the high-speed signals at the outputs. Its bandwidth is quite marginal to pass high-speed USB 2.0 differential signals (480Mbps) with good signal integrity. The WAS7223Q is featured with special circuitry on the D+/D-, which allows the device to withstand a VBUS short to D+ or D- when the USB devices are either powered off or on. The SEL/OE pin has overvoltage protection that allows voltages above VCC, up to 7.0V to be present on the pin without damage or disruption of operation of the part, regardless of the operating voltage. The WAS7223Q is also featured with smart circuitry to minimize VCC leakage current even when SEL/OE control voltage is lower than VCC supply voltage. In other word, there is no need of additional device to shift SEL/OE level to be the same as that of VCC in real application. The WAS7223...
