PI5C3384

Features: 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) – 24-pin 300-mil wide plastic SOIC (S) – 24-pin 173-mil wide plastic TSSOP (L) PI5C3384 PI5C3384C 10-Bit, 2-Port Bus Switch Description: Pericom Semiconductor’s PI5C3384 and PI5C3384C are 10-bit, 2-port bus switches designed with a low On-Resistance 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 (BEx) input signals. Two bus enable signals are provided, one for each of the upper and lower five bits of the two 10-bit buses.
