Product Description

The PI3B34X245 is a 3.3V, 32-bit, 2-port bus switch. Four enable signals (BEn) turn the switches on. The bus switch creates no additional propagational delay or additional ground bounce noise.


  • Fast Switching Speed - 4.5ns max.
  • Near-Zero propagation delay
  • 5-ohm switches connect inputs to outputs
  • Direct bus connection when switches are ON
  • Ultra-low quiescent power (1.0μA typical)
    • Ideally suited for notebook applications
  • Industrial operating temperature: –40°C to +85°C
  • TTL - compatible control of input levels
  • Packaging (Pb-free & Green):
    • 80-pin 150-mil wide plastic BQSOP (B)
