PI3B16862  
PI3B162862 (25)  
3.3V, Hot Insertion, 20-Bit, 2-Port BusSwitch  
Product Features  
Product Description  
Pericom Semiconductor’s PI3B series of Bus Switch circuits are  
produced using the Company’s advanced 0.35 micron CMOS  
technology, achieving industry leading speed.  
• Near-zero propagation delay  
• 5or 25Ω switches connect inputs to outputs  
• Fast Switching Speed - 5ns (max.)  
• Direct bus connection when switches are ON  
• Permits Hot Insertion  
The PI3B16862 is configured as a 3.3 Volt, 20-bit, hot-insertion  
2-port bus switch designed with a low ON resistance (5)  
allowing inputs to be connected directly to outputs. The bus  
switch creates no additional propagational delay or additional  
ground bounce noise. The switch is turned ON by the Bus Enable  
(BEx) input signal.  
• 32X384 function with flow through pinout make board  
layout easier  
• Vcc Operating Range: 3.0V to 3.6V  
• Industrial operating temperature: –40°C to +85°C  
The PI3B162862 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 BQSOP (B)  
– 48-pin 240-mil wide plastic TSSOP (A)  
– 48-pin 300-mil wide plastic SSOP (V)
