DESCRIPTION:
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.
equivalent logic devices.
The QS3257 is a high-speed CMOS LVTTL-compatible Quad 2:1
Mux/Demux devices provide an order of magnitude faster speed than
The QS3257 is characterized for operation at -40°C to +85°C.
