Description

The PI3USB103 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 PI3USB103 offers over voltage protection per the USB 2.0

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

withstand a short to Vbus. If VDD = 0V, the I/Os can still have

signals present, and the signal will NOT leak through to VDD.
