Description
The PI3USB10LP-Ais 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 PI3USB10LP-A 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
offered if a 100-ohm pull up resistor is placed between V_CC pin
to the power supply.
