ditional propagational delay or additional ground bounce noise.
Features
Î Near-Zero propagation delay
Î 5Ω switches connect inputs to outputs
Î Direct bus connection when switches are ON
Î Ultra-low quiescent power (0.2μA typical)
à Ideally suited for notebook applications
Î Industrial operating temperature: –40°C to +85°C
Î Packaging (Pb-free & Green available):
