PI3USB42

Product Description

The PI3USB42 is a single differential channel 2:1 multiplexer/demultiplexer USB 2.0 Switch. Industry leading advantages include a propagation delay of less than 250ps, resulting from its low channel resistance and I/O capacitance. The device multiplexes differential outputs from a USB Host device to one of two corresponding outputs. The switch is bidirectional and offers little or no attenuation of the high-speed signals at the outputs. It is designed for low bit-to-bit skew, high channel-to-channel noise isolation and is compatible with various standards, such as High Speed USB 2.0 (480 Mb/s). The PI3USB42 offers overvoltage protection per the USB2.0 specification. With the chip powered on or off, all I/O pins can withstand a short to Vbus (5V +/-10%). If VDD=0V, the I/Os can still have signals present, and the signal will NOT leak through to VDD.
