Description
The PI3USB10LP-BE is a single differential channel
2:1 multiplexer/demultiplexer USB 2.0 Switch. 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 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).
The PI3USB10LP-BE offers overvoltage protection per
the USB2.0 specification. With the chip powered on or
off, all I/O pins can withstand a short to Vbus (5V +/-
10%). If VDD=0V, the I/Os can still have signals
present, and the signal will NOT leak through to VDD.

3. Measured by the voltage drop between D and Dn pin at indicated current through the Switch On-Resistance is determined
by the lower of the voltages on the two (D, Dn) pins.
Note:
Stresses greater than those listed under
MAXIMUM RATINGS may cause permanent
damage to the device. This is a stress rating only
and functional operation of the device at these or
any other conditions above those indicated in the
operational sections of this specification is not
implied. Exposure to absolute maximum rating
conditions for extended periods may affect
reliability.
The input and output negative voltage ratings
may be exceeded if the input and output diode
current ratings are observed.

Notes:
1. For max. or min. conditions, use appropriate value specified under Electrical Characteristics for the applicable device type.
2. Guaranteed by design.
3. The 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 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.
