DSC-5556/5 c INDUSTRIAL TEMPERATURE RANGE FUNCTIONAL BLOCK DIAGRAM The IDT logo is a registered trademark of Integrated Device Technology, Inc. FEATURES: • Enhanced N channel FET with no inherent diode to Vcc • Bidirectional switches connect inputs to outputs • Zero propagation delay, zero ground bounce • Internal 25Ω Ω Ω Ω Ω resistors for low noise • 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 • Logic replacement (data processing) • Capacitance isolation • Clock gating IDTQS34X2245 QUICKSWITCH® PRODUCTS HIGH-SPEED CMOS QUICKSWITCH 32-BIT MULTIWIDTH™ BUS SWITCHES DESCRIPTION: The QS34X2245 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 worlds first small outline 32-bit solution. The low ON-resistance of the QS34X2245 allows inputs to be connected to outputs without adding propagation delay and without generating additional ground bounce noise. Internal 25 Ω resistors reduce reflection noise in high-speed applications. When Output Enable (OEn) is low, the switches are turned on, connecting bus A to bus B. When OEn is high, the switches are turned off. This device isideallysuitedfor32/64bitapplicationswhereboardspaceisatapremium. QuickSwitch devices provide speeds an order of magnitude faster than conventional logic devices. The QS34X2245 is characterized for operation at -40°C to +85°C.
