3.3V, Wide Bandwidth, 2-Channel,
2:1 Mux/DeMux USB 2.0 Switch w/ Single Enable
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).
