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.
Features
Near-Zero propagation delay
5-ohm switches connect inputs to outputs
Fast Switching Speed: 4.5ns (max.)
Ultra-Low Quiescent Power (0.2μA Typical)
à
Ideally suited for notebook applications
TTL-compatible control of inputs levels
ESD protection (2kV Human Body Model and 200V
Machine Model)
Packaging (Pb-free & Green):
