PI3C32X384  
PI3C32X2384 (25ohm)  
2.5V/3.3V, High Bandwidth, Hot Insertion  
20-Bit, 2-Port, Bus Switch  
Product Description  
PericomSemiconductor’sPI3Cseriesoflogiccircuitsareproduced  
using the Company’s advanced submicron CMOS technology,  
achieving industry performance.  
Product Features  
• Near-zero propagation delay  
• Low noise, 25ohm version (PI3C32X2384)  
• 5ohm switches connect inputs to outputs (PI3C32X384)  
• High Bandwidth (>400 MHz)  
• Permits Hot Insertion.  
• 5V I/O Tolerant  
• 2.5V Supply Voltage Operation  
• Packages available:  
The PI3C32X384, and PI3C32X2384 are 2.5V or 3.3Volt, high-  
bandwidth 20-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  
BusEnable(BE)inputsignal. Fourbusenablesignalsareprovided,  
oneforeachofthe upperandlowerfivebitsofthetwo10-bitbuses.  
The PI3C32X2384 is designed with an internal 25ohm resistor  
reducing noise reflection in high-speed applications.  
– 48-pin 150-mil wide plastic BQSOP (B)  
– 48-pin 240-mil wide plastic TSSOP (A)  
Applications  
• High Bandwidth Data switching  
• Hot Docking
