IDTQS3253 HIGH-SPEED CMOS QUICKSWITCH DUAL 4:1 MUX/DEMUX INDUSTRIAL TEMPERATURE RANGE QUICKSWITCH PRODUCTS IDTQS3253 HIGH-SPEED CMOS QUICKSWITCH DUAL 4:1 MUX/DEMUX DESCRIPTION: FEATURES: Enhanced N channel FET with no inherent diode to Vcc The QS3253 is a high-speed CMOS TTL-compatible dual 4:1 multi- 5 bidirectional switches connect inputs to outputs plexer/demultiplexer with 3-state outputs. The QS3253 is function and Pin compatible with the 74F253, 74FCT253, and 74FCT253T pinout compatible version of the 74F253, 74FCT253, and the 74ALS/AS/ Zero propagation delay, zero ground bounce LS253 dual 4:1 multiplexers. The low ON resistance of the QS3253 allows Undershoot clamp diodes on all switch and control inputs inputs to be connected to outputs without adding propagation delay and TTL-compatible control inputs without generating additional ground bounce noise. Available in QSOP and S1 packages Mux/Demux devices provide an order of magnitude faster speed than equivalent logic devices. The QS3253 is characterized for operation at -40C to +85C. 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 YA I2A I3A I0B I1B YB I2B I3B INDUSTRIAL TEMPERATURE RANGE FEBRUARY 2006 1 c 2011 Integrated Device Technology, Inc.
