PI3B16292  
PI3B162292 (25)  
3.3Volt, 24-Bit  
Mux/Demux BusSwitch  
Features  
Description  
• Near-zero propagation delay  
• 5switches connect inputs to outputs  
• Fast Switching Speed - 5ns (max.)(16292)  
• Internal 500pull-down on A2 ports  
• Ultra-low quiescent power (0.2µA typical) – Ideally  
suited for notebook applications  
• Vcc Operating Range : 3.0V to 3.6V  
• Industrial operating temperature: –40°C to +85°C  
• Make-before-break switching  
PericomSemiconductor’sPI3Bseriesoflogiccircuitsareproduced  
using the Company’s advanced 0.35 micron CMOS technology.  
The PI3B16292 and PI3B162292 are 3.3 volt, 12-bit to 24-bit  
Mux/Demux Bus switches designed with a low ON resistance  
allowing inputs to be connected directly to outputs.  
The PI3B162292 device has a built-in 25-ohm series resistor  
to reduce noise resulting from reflections, thus eliminating the  
need for an external terminating resistor.  
A2 port is not externally connected and, as a result, has an internal  
500-ohm pulldown resistor to ground.  
• Packages available:  
– 56-pin 240-mil wide thin plastic TSSOP (A)  
– 56-pin 300-mil wide plastic SSOP (V)
