The bus switch creates no additional propagational delay or additional ground bounce noise. 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 PI3B32384 is designed with an internal 25-ohm resistor reducing noise reflection in highspeed applications.
