Description
Pericom Semiconductor’s PI3B3245 is a 3.3V 8-bit, 2-port bus
switch designed with a low On-Resistance (5-ohm) allowing in-
puts 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.
