IDTQS3257 Datasheet | Integrated Device

FEATURES : - - - - - - - Enhanced N channel FET with no inherent diode to Vcc 5Ω bidirectional switches connect inputs to outputs Pin patible with the 74F257, 74FCT257, and 74FCT257T Zero propagation delay, zero ground bounce Undershoot clamp diodes on all switch and control inputs TTL-patible control inputs Available in SOIC, QSOP, and S1 packages DESCRIPTION : The QS3257 is a high-speed CMOS LVTTL-patible Quad 2:1 multiplexer/demultiplexer. The QS3257 is a function and pinout patible Quick Switch version of the 74F257, 74FCT257, and the 74ALS/AS/LS257 Quad 2:1 multiplexers. The low ON resistance of the QS3257 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 QS3257 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) Bus funneling FUNCTIONAL BLOCK DIAGRAM E I0A YA I1A I0B YB I1B I0C YC I1C I0D YD I1D The IDT logo is a registered trademark of Integrated Device Technology, Inc.
