PI3B3244  
3.3V, Hot Insertion,  
8-Bit, 2-Port NanoSwitch™  
Description  
Features  
• Near-Zero propagation delay  
• 5-ohm switches connect inputs to outputs when enabled  
• Fast Switching Speed - 4.5ns max.  
PericomSemiconductor’sPI3Bseriesoflogiccircuitsareproduced  
using the Company’s advanced sub-micron CMOS technology,  
achieving industry leading performance.  
The PI3B3244 features a set of 3.3V 8-bit bus switches, which is  
pinout andfunctioncompatiblewiththeP74FCT244T,74F244,and  
74ALS/AS/LS2448-bit drivers. Two enable signals (BEn) turn the  
switches on similar to the enable signals of the 244. The bus switch  
create no additional propagation delay or ground bounce noise.  
• Ultra-LowQuiescentPower(0.2µATypical)  
– Ideally suited for notebook applications  
• Pin compatible with 74 series 244 logic devices  
• Packaging:
