PI5C32X384/32X384C  
20-Bit, 2-Port Bus Switch  
Features  
Description  
• Near-Zero propagation delay  
• 5Ω switches connect inputs to outputs  
• Direct bus connection when switches are ON  
Pericom Semiconductor’s PI5C32X384 and PI5C32X384C are  
20-bit bus switches designed with a low On-Resistance allowing  
inputstobeconnecteddirectlytooutputs.Thebusswitchcreatesno  
additional propagational delay or additional ground bounce noise.  
The switches are turned ON by the Bus Enable (BE) input signal.  
Four bus enable signals are provided, one for each of the upper  
and lower five bits of the two 10-bit buses.  
• Ultra-low quiescent power 32X384 (0.2µA typical)  
– Ideally suited for notebook applications  
• Packaging (Pb-free & Green Available):  
– 48-pin 150-mil wide plastic BQSOP (B)  
– 48-pin 240-mil wide plastic TSSOP (A)
