  • Permits Hot Insertion
  • Near-zero propagation delay
  • 5Ω 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
  • Packages (Pb-free & Green available):
    • 40-pin, 150-mil wide plastic BQSOP (B)
