10-Bit, 2-Port, Bus Switch
Description
The PI3C3861 is a 10-bit, 2.5volt or 3.3 volt, 2-port bus switch
designed with a low On-Resistance (5-ohm) 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).
