Diodes' PI5C3390 and PI5C32390 are 16-to-8 multiplexer/demultiplexer bus switches with a low On-Resistance allowing inputs to be connected directly to outputs. The two enable inputs connect
each of eight I/O to the common I/O pin. This multiplexer function can be used to select and route logic signals to form crossbar switches, isolate bus capacitance, or provide a zero delay switch
connection. The bus switch creates no additional ground bounce noise or additional propagation delay. The PI5C32390 is designed with an internal 25-ohm resistor reducing noise reflection in high-speed applications.


  • Near-Zero propagation delay
  • Low noise, 25Ω version (PI5C32390)
  • 5Ω switches connect inputs to outputs (PI5C3390)
  • Direct bus connection when switches are ON
  • Ultra-low quiescent power (0.2μA typical)
    • Ideally suited for notebook applications
  • Packaging (Pb-free & Green):
    • 28-pin QSOP (Q)
