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.
