Product Description
Pericom Semiconductors PI5C series of logic circuits are produced
using the Companys 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.
