PI5C3384
PI5C3384C
10-Bit, 2-Port Bus Switch
Features:
Description:
• 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)
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.
