Product Description

Pericom Semiconductor’s PI5C series of logic circuits are produced

using the Company’s advanced submicron CMOS technology,

achieving industry performance.

The PI5C3384A is a 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 (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.
