PI3USB20
3.3V, Wide Bandwidth, 4-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 PI3USB20 is a 8- to 4-Channel multiplexer/demultiplexerVideo
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 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).

Notes:
1. For max. or min. conditions, use appropriate value specified under Electrical Characteristics for the applicable device type.
2. Typical values are at VCC = 3.3V, TA = 25°C ambient and maximum loading.
3. Measured by the voltage drop between A and B pins at indicated current through the switch. On-Resistance is determined by the lower of the
voltages on the two (A & B) pins.
4. This parameter is determined by device characterization but is not production tested.
