PI3B3384

PI3B32384 (25Ω)

3.3V, 10-Bit, 2-Port, NanoSwitch™

Description

Features

• Near-Zero propagation delay

PericomSemiconductor’sPI3B3384andPI3B32384are3.3Volt,10-

bit,2-portbusswitchesdesignedwithalowOn-Resistance allowing

inputs to be connected directly to outputs. The bus switch creates

no additional propagational delay or additional ground bounce

noise. Switches are turned ON by the Bus Enable (BE) input signal.

Two bus enable signals are provided, one for each of the upper and

lower five bits of the two 10-bit buses. The PI3B32384 is designed

with an internal 25-ohm resistor reducing noise reflection in high-

speed applications.

• Lownoise,25-ohmversion(PI3B32384)

• 5-ohm switches connect inputs to outputs (PI3B3384)

•
