IDTQS3253 HIGH-SPEED CMOS QUICKSWITCH DUAL 4:1 MUX/DEMUX INDUSTRIAL TEMPERATURE RANGE QUICKSWITCH® PRODUCTS HIGH-SPEED CMOS QUICKSWITCH DUAL 4:1 MUX/DEMUX FEATURES: IDTQS3253 DESCRIPTION: Enhanced N channel FET with no inherent diode to Vcc 5Ω bidirectional switches connect inputs to outputs 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 SOIC, QSOP, and S1 packages 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. 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 I 0A I 1A YA I 2A I 3A I 0B YB I 1B I 2B I 3B The IDT logo is a registered trademark of Integrated Device Technology, Inc.
