PI5C32X384/32X384C
20-Bit, 2-Port Bus Switch
Description
Pericom Semiconductor’s PI5C32X384 and PI5C32X384C are
20-bit bus switches designed with a low On-Resistance 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.
Four bus enable signals are provided, one for each of the upper
and lower five bits of the two 10-bit buses.
