PI5C32X2384  
20-Bit Bus Switch with 25Series Resistor  
Product Description  
Product Features  
Pericom Semiconductor’s PI5C series of BusSwitch circuits are  
produced in the Company’s advanced sub-micron CMOS  
technology, achieving industry leading performance.  
• Near-zero propagation delay  
• 25series resistor  
• 5switches connect inputs to outputs  
• Direct bus connection when switches are ON  
The PI5C32X2384 is a 20-bit 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 (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.  
There is an internal 25series resistor to reduce noise reflection in  
high-speed applications.  
• Ultra-low quiescent power 32X2384 (0.2µA typical)  
– Ideally suited for notebook applications  
• Packages available:  
– 48-pin 150-mil wide plastic BQSOP (B)  
– 48-pin 240-mil wide plastic TSSOP (A)
