PI3USB10M
4.2V, Wide Bandwidth, 2-Channel,
2:1 Mux/DeMux USB 2.0 Switch w/ Single Select
Features
Description
• USB 2.0 compliant
The PI3USB10M is a single differential channel 2:1 multiplexer/
demultiplexer USB 2.0 Switch. Industry leading advantages in-
clude 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 cor-
responding 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).
• R is 4Ω typical
ON
• Low bit-to-bit skew
• Low Crosstalk: -31dB @ 250MHz
• Near-Zero propagation delay: 250ps
• Switching speed: 9ns
• Channel On Capacitance: 6pF (typical)
• V Operating Range: 2.7V to 4.2V ±10%
CC
• ESD>2000V . . . Human Body Model
• >700 MHz bandwidth (or data frequency)
• Packaging (Pb-free & Green):

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 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.

Waveform 1 is for an output with internal conditions such that the output is low except when disabled by the output control.
Waveform 2 is for an output with internal conditions such that the output is high except when disabled by the output control.
All input impulses are supplied by generators having the following characteristics: PRR ≤ MHz, ZO = 50Ω, tR ≤ 2.5ns, tF ≤ 2.5ns.
The outputs are measured one at a time with on transition per measurement.

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.
