Product Description

PericomSemiconductor’sPI3Cseriesoflogiccircuitsareproduced

using the Company’s 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.
