2.5V/3.3V, High Bandwidth, Hot Insertion
8-Bit, 2-Port, Bus Switch
Description
Features
• Near-Zero propagation delay
• 5-ohm switches connect inputs to outputs
• HighBandwidthOperation(>400MHz)
• Permits Hot Insertion
PericomSemiconductor’s PI3C3245is a 2.5volt or 3.3 volt 8-bit,
2-port bus switch designed with a low On-Resistance (5-ohm)
allowing inputs to be connected directly to outputs. The bus switch
creates no additional propagational delay or additional ground
bounce noise. The switches are turned ON by the Bus Enable (BE)
input signal. It is very useful in switching signals that have high
bandwidth(>400MHz).

Notes:
1. This parameter is guaranteed but not tested on Propagation Delays.
2. 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 50pF 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 interaction with the load on the driven side.
