PI3C3384
2.5V/3.3V, High Bandwidth, Hot Insertion
10-Bit, 2-Port, Bus Switch
Description
Pericom Semiconductor’s PI3C3384 is a 2.5V or 3.3V, high
bandwidth 10-bit, 2-port bus switches designed with a low On-
Resistanceallowing 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. Two bus enable signals are
provided, one for each of theupper and lower five bits of the
two 10-bit buses.
Applications
• High Bandwidth Data switching
• Hot Docking
