PI3B16212  
PI3B162212 (25)  
3.3V, 24-Bit Bus Exchange Switch  
Product Features  
Product Description  
• Near-zero propagation delay  
Pericom Semiconductor’s PI3B series of logic circuits are produced  
in the Company’s advanced 0.35 micron CMOS technology.  
• 5switches connect inputs to outputs  
• Direct bus connection when switches are ON  
• Fast Switching Speed - 5ns (max.)  
• VCC Operating Range: 3.0V to 3.6V  
• Industrial operating temperature: –40°C to +85°C  
The PI3B16212 and PI3B162212 are 3.3 volt, 24-bit bus exchange  
switches designed with a low ON resistance allowing inputs to be  
connected directly to outputs. The devices operate as a 24-bit bus  
switch or as a 12-bit exchanger, providing data exchange between  
the four signal ports via the data select pins (S0-S2).  
• Packages available:  
The PI3B162212 device has a built-in 25-ohm series resistor to  
reduce noise due to reflections, thus eliminating the need for an  
external terminating resistor.  
– 56-pin 240-mil wide thin plastic TSSOP (A)  
– 56-pin 300-mil wide plastic SSOP (V)
