Description
The PI3USB102 is a single differential channel 2:1 multiplexer/de-
multiplexer 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 PI3USB102 offers over voltage protection per the USB 2.0
specifi cation. With the chip powered on or off, all I/O pins can
withstand a short to Vbus (5V +/-10%). This feature can only be
offered if a 100-ohm pull up resistor is placed between VDD pin
to the power supply.
In situations where Vbus can be as high as 7V, Pericom recommends
changing the resistor value from 100ohm to 200ohm. Pericom can
still support over-voltage protection up to 7V, as long as the 200ohm
resistor is present.

Notes:
1. For max. or min. conditions, use appropriate value specifi ed 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.

Applications Information
Logic Inputs
The logic control inputs can be driven up to +3.6V regardless of the supply voltage. For example, given a +3.3V supply, the output
enables or select pins may be driven low to 0V and high to 3.6V. Driving IN Rail-to-Rail® minimizes power consumption.
Power Supply Sequencing
Proper power supply sequencing is recommended for all CMOS devices. Always apply VDD and GND before applying signals to
input/output or control pins.
