QUAD 2:1 MUX/DEMUX

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.
