IDTQSIDTQS32XL384 HIGH-SPEED CMOS 20-BIT BUS SWITCH INDUSTRIAL TEMPERATURE RANGE QUICKSWITCH® PRODUCTS HIGH-SPEED CMOS 20-BIT BUS SWITCH DESCRIPTION: FEATURES: • • • • • • • The QS32XL384 provides a set of twenty high-speed CMOS TTLcompatible bus switches. The low ON resistance of the QS32XL384 allows inputs to be connected to outputs without adding propagation delay and without generating additional ground bounce noise. The Bus Enable (BE) signals turn the switches on. Four Bus Enable signals are provided, one for each of five bits of the 20-bit bus. The ‘384 family of QuickSwitch products is ideal for switching wide digital buses, as well as hot-docking, 5V to 3V conversion and capacitance isolation for power conservation. The QS32XL384 is characterized for operation at -40°C to +85°C. Enhanced N channel FET with no inherent diode to VCC Ω bidirectional switches connect inputs to outputs 5Ω Zero propagation delay, zero ground bounce Undershoot Clamp Diodes on all switch and control Inputs Four enables control five bits each TTL-compatible input and output levels Available in 48-pin QVSOP package APPLICATIONS: • • • • • • • • IDTQS32XL384 Hot-swapping, hot-docking Voltage translation (5V to 3.3V) Logic replacement (data processing) Power conservation Capacitance reduction and isolation Low power for hand held and mobile applications Bus isolation Clock gating FUNCTIONAL BLOCK DIAGRAM A0 B0 A10 B10 A4 B4 A14 B14 A5 B5 A15 B15 A9 B9 A19 B19 BEA BEC BED BEB IDT and the IDT logo is a registered trademarks of Integrated Device Technology, Inc.

The time constant for the switch alone is of the order of 0.25ns at CL = 50pF. 4. The bus switch contributes no propagation delay other than the RC delay of the ON resistance of the switch and the load capacitance. Since this time constant is much smaller than the rise and fall times of typical driving signals, it adds very little propagation delay to the system. Propagation delay of the bus switch, when used in a system, is determined by the driving circuit on the driving side of the switch and its interaction with the load on the driven side. 4 IDTQSIDTQS32XL384 HIGH-SPEED CMOS 20-BIT BUS SWITCH INDUSTRIAL TEMPERATURE RANGE ORDERING INFORMATION QS XXXXX Device Type XX Package X Process X 5 Blank 8 Tube or Tray Tape and Reel Blank Industrial (-40°C to +85°C) Q1G 48-Pin QVSOP - Green 32XL384 High Speed 20-Bit Bus Switch IMPORTANT NOTICE AND DISCLAIMER RENESAS ELECTRONICS CORPORATION AND ITS SUBSIDIARIES (“RENESAS”) PROVIDES TECHNICAL SPECIFICATIONS AND RELIABILITY DATA (INCLUDING DATASHEETS), DESIGN RESOURCES (INCLUDING REFERENCE DESIGNS), APPLICATION OR OTHER DESIGN ADVICE, WEB TOOLS, SAFETY INFORMATION, AND OTHER RESOURCES “AS IS” AND WITH ALL FAULTS, AND DISCLAIMS ALL WARRANTIES, EXPRESS OR IMPLIED, INCLUDING, WITHOUT LIMITATION, ANY IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, OR NON-INFRINGEMENT OF THIRD PARTY INTELLECTUAL PROPERTY RIGHTS.
