DESCRIPTION
:
The QS33X257 is a high-speed CMOS TTL-patible 24:12 multiplexer/demultiplexer. The QS33X257 is functionally patible to three of the Quick Switch version of the 74F257, 74FCT257, and the 74ALS/AS/ LS257 Quad 2:1 multiplexers. The low ON resistance of the QS33X257 allows inputs to be connected to outputs without adding propagation delay and without generating additional ground bounce noise....
