Description
Pericom Semiconductor’s PI3C32X384, is a 2.5V or 3.3Volt, high-
bandwidth 20-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. Four bus enable signals are provided, one for each
of the upper and lower five bits of the two 10-bit buses.
