QS3383QG8

IDTQS3383 HIGH-SPEED CMOS 10-BIT BUS EXCHANGE SWITCH INDUSTRIAL TEMPERATURE RANGE QUICKSWITCH® PRODUCTS HIGH-SPEED CMOS 10-BIT BUS EXCHANGE SWITCH DESCRIPTION: FEATURES: • • • • • • The QS3383 provides ten high-speed CMOS TTL-compatible bus switches. The low ON resistance of the QS3383 allows inputs to be connected to outputs without adding propagation delay and without generating additional ground bounce noise. The Bus Enable (BE) signal turns the switches on. The Bus Exchange (BX) signal provides nibble swap of the AB and CD pairs of signals. This exchange configuration allows byte swapping of buses in systems. It can also be used as a 5-wide 2-to-1 multiplexer and to create low delay barrel shifters, etc. The QS3383 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 added ground bounce Undershoot clamp diodes on all switch and control inputs Bus exchange allows nibble swap Available in QSOP package APPLICATIONS: • • • • IDTQS3383 Hot-swapping, hot-docking Voltage translation (5V to 3.3V) Resource sharing Crossbar switching FUNCTIONAL BLOCK DIAGRAM A0 C0 B0 D0 A4 C4 B4 D4 BX BE INDUSTRIAL TEMPERATURE RANGE c 2011 Integrated Device Technology, Inc.

Minimums are guaranteed but not production tested. 2. This parameter is guaranteed but not production tested. 3. 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 IDTQS3383 HIGH-SPEED CMOS 10-BIT BUS EXCHANGE SWITCH INDUSTRIAL TEMPERATURE RANGE ORDERING INFORMATION QS XXXXX Device Type XX Package X Process X Blank 8 Tube or Tray Tape and Reel Blank Industrial (-40°C to +85°C) QG Quarter Size Outline Package - Green 3383 High Speed CMOS 10-Bit Bus Exchange Switch 5 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.
