Overview

DM74ALS257 • DM74ALS258 3-STATE Quad 1-of-2-Line Data Selector/Multiplexer April 1984 Revised February 2000 DM74ALS257 • DM74ALS258 3-STATE Quad 1-of-2-Line Data Selector/Multiplexer General Description These data selectors/multiplexers contain inverters and drivers to supply full on-chip data selection to the four 3STATE outputs that can interface directly with data lines of bus-organized systems.
A 4-bit word selected from one of two sources is routed to the four outputs.
The DM74ALS257 presents true data whereas the DM74ALS258 presents inverted data to minimize propagation delay time.
This 3-STATE output feature means that n-bit (paralleled) data selectors with up to 258 sources can be...
