Description
The PI3USB40 is a 16- to 8-channel multiplexer/demultiplexer
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 multiplexes
differential outputs from a USB transceiver 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).

Notes:
1. For Max. or Min. conditions, use appropriate value specied under Electrical Characteristics for the applicable device type.
2. Guaranteed by design.
3. The bus switch contributes no propagational delay other than the RC delay of the On-Resistance of the switch and the load capacitance. The
time constant for the switch alone is of the order of 0.25ns for 10pF load. Since this time constant is much smaller than the rise/fall times of
typical driving signals, it adds very little propagational delay to the system. Propagational delay of the bus switch when used in a system is
determined by the driving circuit on the driving side of the switch and its interactions with the load on the driven side.
