10-Bit, 2-Port BusSwitch
Product Description:
Pericom Semiconductor’s PI5C series of logic circuits are pro-
duced in the Company’s advanced sub-micron CMOS technology,
achieving industry performance.
The PI5C3384, PI5C3384C, and PI5C32384 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 (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. The PI5C32384 is designed with an internal
25Ω resistor reducing noise reflection in high-speed applications.
