PI5C16861C  
PI5C162861C (25)  
20-Bit, 2-Port Bus Switch  
Product Features  
Product Description  
Near-zero propagation delay  
Pericom Semiconductor’s PI5C series of Bus Switch circuits are  
produced using the Company’s advanced submicron CMOS  
technology, achieving industry leading speed.  
5or 25Ω switches connect inputs to outputs  
Direct bus connection when switches are ON  
The PI5C16861C is configured as a 20-bit, 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  
propagationaldelayoradditionalgroundbouncenoise.Theswitches  
are turned ON by the Bus Enable (BEx) input signal.  
32X384 function with flow through pinout  
make board layout easier  
Ultra-low quiescent power (105µA typical)  
– ideally suited for notebook applications  
Industrial operating temperature: –40°C to +85°C  
The PI5C162861C 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 240-mil wide plastic TSSOP (A)  
– 48-pin 300-mil wide plastic SSOP (V)
