Product Description

The PI3B3245 is a 3.3V 8-bit, 2-port bus switch designed with a low On-Resistance (5-ohm) 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.

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 QSOP (Q)
    • 20-pin TSSOP (L)
    • 20-pin SOIC (S)
