Description

The PI3USB102J is a single differential channel 2:1 multiplexer/demultiplexer USB 2.0 Switch. Industry leading advantages include a propagation delay of  250ps, resulting from its low channel resistance and  I/O capacitance. PI3USB102J 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 PI3USB102J offers over voltage protection for the Y+/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%) a less than 3.6V signal will transmit through M+/M- and D+/D- outputs after 300ns.
