The QS3257 is a high-speed CMOS LVTTL -compatible Quad 2:1 multiplexer/demultip
lexer. 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. The QS3257 operates at -40C to +85C.
