Product Description
Pericom Semiconductors PI3C series of logic circuits are produced
using the Companys advanced submicron CMOS technology,
achieving industry performance.
The PI3C3384, and PI3C32384 are 2.5V or 3.3Volt, high bandwidth
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
PI3C32384 is designed with an internal 25Ω resistor reducing
noise reflection in high-speed applications.
