Block Diagram
Description
Pericom Semiconductor’s PI3B16861 is configured as a 3.3 volt, hot-
insertion, 20-bit, 2-port bus switch designed with a low On-Resistance
(5-ohms) allowing inputs to be connected directly to outputs. The
bus switch creates no additional propagational delay or additional
ground bounce noise. The switch is turned ON by the Bus Enable
(BEx) input signal.
