Product Description

The PI3C32X384, is a 2.5V or 3.3Volt, highbandwidth 20-bit, 2-port bus switches designed with a low Onresistance 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. Four bus enable signals are provided, one for each of the upper and lower five bits of the two 10-bit buses.
