Description

Pericom Semiconductor’s PI3USB series of logic circuits are

produced using the Company’s advanced sub-micron CMOS

technology, achieving industry leading performance.

The PI3USB10 is a 4- to 2-Channel multiplexer/demultiplexer

USB 2.0 Switch with Hi-Z outputs. Industry leading advantages

include a propagation delay of less than 250ps, resulting from its

low channel resistance and I/O capacitance. The device multi-

plexes 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).
