H = High Voltage Level L = Low Voltage level Hi-Z = High Impedance Description Pericom Semiconductor’s PI3B32X384 is a 3.3V, 20-bit bus switch 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. Four bus enable signals are provided, one for each of the upper and lower five bits of the two 10-bit buses.
