PI5C3244  
8-Bit, 2-Port Switch  
Features:  
Description:  
• Near-Zero propagation delay  
Pericom Semiconductor’s PI5C3244 features a set of eight bus  
switches which is pinout and function compatible with the  
PI74FCT244T, 74F244, and 74ALS/AS/LS 244 8-bit drivers. Two  
enable signals (BEn) turn the switches on similar to the enable  
signalsofthe244. Thebusswitchcreatesnoadditionalpropagation  
delay or ground bounce noise.  
• 5-ohm switches connect inputs to outputs when enabled  
Direct bus connection when switches are ON  
UltraLowQuiescentPower(0.2µATypical)  
– Ideally suited for notebook applications  
Pin compatible with 74 Series 244 logic devices  
• Packaging(Pb-free&Greenavailable):  
– 20-pin173-milwideplasticTSSOP(L)  
– 20-pin150-milwideplasticQSOP(Q)  
– 20-pin300-milwideplasticSOIC(S)
