PI3B162210 (25)  
3.3V, Hot Insertion 20-Bit, 2-Port BusSwitch  
Product Features  
Product Description  
• Near-zero propagation delay  
• 5or 25Ω switches connect inputs to outputs  
• Fair Switching Speed - 4.5ns max.  
Pericom Semiconductor’s PI3B series of BusSwitch circuits are  
produced in the Company’s advanced 0.35 micron CMOS  
technology, achieving industry leading speed.  
The PI3B16210 is configured as 3.3 volt 20-bit, 2-port bus  
switches designed with a low ON resistance (5) allowing inputs  
to be connected directly to outputs. The bus switch creates no  
additionalpropagationaldelayoradditionalgroundbouncenoise.

• 32X384 function with flow through pinout make board  
layout easier  
• Permits Hot Insertion.  
• Vcc Operating Range: 3.0V to 3.6V  
• Industrial operating temperature: –40°C to +85°C  
The PI3B162210 device has a built-in 25-ohm series resistor to  
reduce noise resulting from reflections, thus eliminating the need  
for an external terminating resistor.  
• Packages available:  
– 48-pin 150-mil wide plastic QSOP (B)  
– 48-pin 240-mil wide plastic TSSOP (A)  
– 48-pin 300-mil wide plastic SSOP (V)
