The PI3C34X245 is a 2.5V or 3.3V, 32-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 switches are turned ON by the Bus Enable (BE) input signal. It is very useful in switching signals that have high bandwidth (>400 MHz).


  • Near-Zero propagation delay
  • 5-ohm switches connect inputs to outputs
  • 2.5V Supply Voltage Operation
  • Permits Hot Insertion
  • Capable of Hot-Swapping
  • 5V I/O Tolerant
  • High Bandwidth Operation (>400 MHz)
  • Packaging (Pb-free & Green):
    • 80-pin 150-mil wide plastic BQSOP (B)
