Description

The PI3USB102G is a single differential channel 2:1 multiplexer/

demultiplexerUSB2.0Switch.Industryleadingadvantagesinclude

a propagation delay of 250ps, resulting from its low channel re-

sistance and I/O capacitance. PI3USB102G is bidirectional and

offers very little attenuation of high-speed signals. 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 PI3USB102G offers over voltage protection for theY+/Y- pins

as per the USB 2.0 specification. With the chip powered on or off if

Y+/Y- pins are shorted to VBUS (5V +/- 5%), M+/M- and D+/D-

outputs are clamped to provide voltage protection for downstream

devices.

The PI3USB102G has a better Y+/Y- power-off leakage current

with the voltage range of 0V to 5V versus 0V to 3.3V for the

PI3USB102E.
