IDTQS3253 HIGH-SPEED CMOS QUICKSWITCH DUAL 4:1 MUX/DEMUX INDUSTRIAL TEMPERATURE RANGE QUICKSWITCH® PRODUCTS HIGH-SPEED CMOS QUICKSWITCH DUAL 4:1 MUX/DEMUX DESCRIPTION: FEATURES: • • • • • • • IDTQS3253 The QS3253 is a high-speed CMOS TTL-compatible dual 4:1 multiplexer/demultiplexer with 3-state outputs. The QS3253 is function and pinout compatible version of the 74F253, 74FCT253, and the 74ALS/AS/ LS253 dual 4:1 multiplexers. The low ON resistance of the QS3253 allows inputs to be connected to 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 QS3253 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 Pin compatible with the 74F253, 74FCT253, and 74FCT253T Zero propagation delay, zero ground bounce Undershoot clamp diodes on all switch and control inputs TTL-compatible control inputs Available in QSOP and S1 packages APPLICATIONS: • • • • • • Logic replacement Video, audio, graphics switching, muxing Hot-swapping, hot-docking Voltage translation (5V to 3.3V) Power conservation Bus funneling FUNCTIONAL BLOCK DIAGRAM S0 S1 EA EB I0A I1A I2A YA I3A I0B I1B I2B YB I3B INDUSTRIAL TEMPERATURE RANGE c 2011 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 for 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 IDTQS3253 HIGH-SPEED CMOS QUICKSWITCH DUAL 4:1 MUX/DEMUX INDUSTRIAL TEMPERATURE RANGE ORDERING INFORMATION QS XXXXX Device Type XX Package X Blank 8 Tube or Tray Tape and Reel QG S1G Quarter Size Outline Package - Green Small Outline IC - Green 3253 High Speed CMOS Quickswitch Dual 4:1 Mux/Demux Datasheet Document History 02/14/2011 Pg. 5 Updated the ordering information by removing the "IDT" notation, non RoHS part and by adding Tape and Reel information. 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.
