PI5C3384
PI5C3384C
10-Bit, 2-Port Bus Switch
Description:
Pericom Semiconductor’s PI5C3384 and PI5C3384C are 10-bit,
2-port 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 (BEx) input
signals. Two bus enable signals are provided, one for each of the
upper and lower five bits of the two 10-bit buses.
