Description

The PI3USB102 is a single differential channel 2:1 multiplexer/

demultiplexer USB 2.0 Switch. Industry leading advantages in-

clude 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 cor-

responding 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 PI3USB102 offers overvoltage protection per the USB 2.0

specification. With the chip powered on or off, all I/O pins can

withstand a short to Vbus (5V +/-10%). This feature can only be

to the power supply.
