Description
e PI3B3245 is a 3.3V 8-bit, 2-port bus switch designed with a
low On-Resistance (5-ohm) allowing inputs to be connected di-
rectly to outputs. e bus switch creates no additional propaga-
tional delay or additional ground bounce noise. e 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)
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):
20-pin SOIC (S)
