3.3V, 20-Bit, 2-Port NanoSwitch
ProductFeatures
ProductDescription
Near-zero propagation delay
Pericom Semiconductors PI3B series of Bus Switch circuits are
produced using the Companys advanced submicron CMOS
technology, achieving industry leading speed.
5 ohms or 25 ohms switches connect inputs to outputs
Fast Switching Speed - 5ns (max.)
Direct bus connection when switches are ON
32X384 function with flow through pinout make board
layout easier
PI3B16862 is configured as a 3.3 Volt, 20-bit, hot-insertion 2-port
bus switch designed with a low ON resistance (5 ohms) allowing
inputs to be connected directly to outputs. The bus switch creates
no additional propagational delay or additional ground bounce
noise.TheswitchisturnedONbytheBusEnable(BEx)inputsignal.

3. Measured by the voltage drop between A and B pin 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.

Notes:
1. See test circuit and waveforms.
2. This parameter is guaranteed but not tested on Propagation Delays.
3. 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.
