IDTQS3251 HIGH-SPEED CMOS QUICKSWITCH 8:1 MUX/DEMUX INDUSTRIAL TEMPERATURE RANGE QUICKSWITCH® PRODUCTS HIGH-SPEED CMOS QUICKSWITCH 8:1 MUX/DEMUX FEATURES: IDTQS3251 Enhanced N channel FET with no inherent diode to Vcc 5Ω bidirectional switches connect inputs to outputs Pin compatible with the 74F251, 74FCT251, and 74FCT251T Zero propagation delay, zero ground bounce Undershoot clamp diodes on all switch and control inputs TTL-compatible control inputs Available in SOIC and QSOP packages DESCRIPTION: The QS3251 is a high-speed CMOS TTL-compatible 8:1 multiplexer/ demultiplexer. The QS3251 has 3-state outputs. The QS3251 is a function and pinout compatible version of the 74F251, 74FCT251 and the 74ALS/ AS/LS251 8:1 multiplexers. The low ON resistance of the QS3251 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 QS3251 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) FUNCTIONAL BLOCK DIAGRAM S0 S1 S2 E I0 I1 I2 Y I3 I4 I5 I6 I7 The IDT logo is a registered trademark of Integrated Device Technology, Inc.
