Description

    The QS3257 is a high-speed CMOS LVTTL-compatible Quad  2:1 multiplexer/demultiplexer. The QS3257 is a function and pinout compatible QuickSwitch 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 IDTQS3257 provide an order of magnitude faster speed than equivalent logic devices.

    The QS3257 is characterized for operation at -40 to +85
