QUICKSWITCH® PRODUCTS  
IDTQS34X245  
HIGH-SPEED CMOS  
QUICKSWITCH 32-BIT  
MULTIWIDTH™ BUS SWITCHES  
DESCRIPTION:  
FEATURES:  
The QS34X245 is a member of the MultiWidthTM family of QuickSwitch  
devicesandprovidesasetof32high-speedCMOScompatiblebusswitches  
in a flow-through pinout. This device is available in the MilliPaQ package,  
the world's first small outline 32-bit solution. The low ON-resistance of the  
QS34X245allowsinputstobeconnectedtooutputswithoutaddingpropa-  
gationdelayandwithoutgeneratingadditionalgroundbouncenoise. When  
Output Enable (OEn) is low, the switches are turned on, connecting bus A  
tobusB. WhenOEnishigh,theswitchesareturnedoff.Thisdeviceisideally  
suited for 32/64 bit applications where board space is at a premium.  
QuickSwitch devices provide speeds an order of magnitude faster than  
conventionallogicdevices.  
• Enhanced N channel FET with no inherent diode to Vcc  
• Bidirectional switches connect inputs to outputs  
• Zero propagation delay, zero ground bounce  
• QS34X245 is 32-bit version of QS3245  
• Flow-through pinout for easy layout  
• Undershoot clamp diodes on all switch and control inputs  
• TTL-compatible control inputs  
• Available in 80-pin MilliPaQ™ package  
APPLICATIONS:  
• Hot-swapping, hot-docking  
• Voltage translation (5V to 3.3V)  
• Bus switching and isolation  
• Power conservation  
The QS34X245 is characterized for operation at -40°C to +85°C.  
• Logic replacement (data processing)  
• Capacitance isolation  
• Clock gating
