| IDTQS3390 HIGH-SPEED CMOS QUICKSWITCH 16:8 MULTIPLEXER INDUSTRIAL TEMPERATURE RANGE QUICKSWITCH(R) PRODUCTS HIGH-SPEED CMOS QUICKSWITCH 16:8 MULTIPLEXER FEATURES: * * * * * * * * IDTQS3390 Enhanced N channel FET with no inherent diode to Vcc 16:8 multiplexer function with zero delay 5 bidirectional switches connect inputs to outputs Zero propagation delay, zero ground bounce Low power CMOS proprietary technology Undershoot clamp diodes on all switch and control inputs Direct bidirectional connection for mux, demux Available in SOIC and QSOP packages DESCRIPTION: The QS3390 provides a 16:8 multiplexer logic switch. The low ON resistance (5) of the QS3390 allows inputs to be connected to the outputs without adding propagation delay and without generating additional ground bounce noise. Mux/Demux devices provide an order of magnitude faster speed than equivalent logic devices. The QS3390 is characterized for operation at -40C to +85C. APPLICATIONS: * Video, audio, graphics switching, muxing * Hot-swapping, hot-docking * Voltage translation (5V to 3.3V) FUNCTIONAL BLOCK DIAGRAM A0 AB 0 A7 AB 7 AE N B0 B7 BE N The IDT logo is a registered trademark of Integrated Device Technology, Inc.

The bus switch contributes no propagation delay other than the RC delay of the ON resistance of the switch and the load capacitance. The time constant for the switch alone is of the order of 0.25ns at CL = 50pF. 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 IDTQS3390 HIGH-SPEED CMOS QUICKSWITCH 16:8 MULTIPLEXER INDUSTRIAL TEMPERATURE RANGE ORDERING INFORMATION IDTQS XXXXX Device Type XX Package X Process Blank Industrial (-40C to +85C) SO Q QG 3390 Small Outline IC Quarter Size Outline Package QSOP - Green High Speed CMOS QuickSwitch 16:8 Multiplexer CORPORATE HEADQUARTERS 2975 Stender Way Santa Clara, CA 95054 for SALES: 800-345-7015 or 408-727-6116 fax: 408-492-8674 www.idt.com for Tech Support: logichelp@idt.com (408) 654-6459 5 |
