Product Description
Pericom聮s Semiconductor聮s PI3C series of logic circuits are produced
using the Company聮s advanced submicron CMOS technology,
achieving industry leading performance.
The PI3C3861 is a 10-bit, 2.5V or 3.3 volt, 2-port bus switch designed
with a low ON resistance (5鈩? 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. This device is
very userful in switching signals that have high bandwidth (>400
MHz).
Applications
聲 High bandwidth data switching
