Product Description

The PI5C3861 is a 10-bit, 2-port bus switch designed with a low On-Resistance (5Ω) allowing inputs to be connected directly to outputs. The bus switch creates no additional propagation delay or additional ground bounce noise. The switches are turned ON by the Bus Enable (BE) input signal.


  • Near-Zero propagation delay
  • 5Ω switches connect inputs to outputs
  • Direct bus connection when switches are ON
  • Ultra Low Quiescent Power (0.2μA typical)
    • Ideally suited for notebook applications
  • Packaging (Pb-free & Green available):
    •  24-pin, 150-mil wide plastic QSOP (Q)
