HIGH-SPEED CMOS  
IDTQS3R245  
QUICKSWITCH 8-BIT LOW  
RESISTANCE BUS SWITCH  
DESCRIPTION:  
FEATURES:  
TheQS3R245providesasetofeighthigh-speedCMOSTTL-compatible  
bus switches in a pinout compatible with 74FCT245, 74F245, 74ALS/AS/  
LS245 8-bit transceivers. The low ON resistance of the QS3R245 allows  
inputs to be connected to outputs without adding propagation delay and  
withoutgeneratingadditionalgroundbouncenoise.TheOutputEnable(OE)  
signal turns the switches on similar to the OEsignal of the 74’245. The low  
ONresistanceofQS3R245makesitidealforPCIhotdockingapplications.  
QuickSwitch devices provide an order of magnitude faster speed than  
conventionallogicdevices.  
• Enhanced N channel FET with no inherent diode to Vcc  
• 5bidirectional switches connect inputs to outputs  
• Pin compatible with the 74F245, 74FCT245, and 74FCT245T  
• Zero propagation delay, zero ground bounce  
• Undershoot clamp diodes on all switch and control inputs  
• TTL-compatible control inputs  
• Available in SOIC and QSOP packages  
The QS3R245 is characterized for operation at -40°C to +85°C.  
APPLICATIONS:  
• Hot-swapping and hot-docking (low resistance for PCI and  
Compact PCI applications)  
• Bus switching and isolation  
• Voltage translation (5V to 3.3V)  
• Capacitance reduction and isolation  
• Power conservation  
• Logic replacement (data processing)  
• Clock gating
