The PI3USB102 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 PI3USB102 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 (5V +/-10%). This feature can only be offered if a 100-ohm pull up resistor is placed between VDD pin to the power supply. In situations where Vbus can be as high as 7V, Diodes recommends changing the resistor value from 100ohm to 200ohm. Diodes can still support over-voltage protection up to 7V, as long as the 200ohm resistor is present.
