General Description

These data selectors/multiplexers contain inverters and

drivers to supply full on-chip data selection to the four

3-STATE 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 propa-

gation delay time.

This 3-STATE output feature means that n-bit (paral-

leled) data selectors with up to 258 sources can be

implemented for data buses. It also permits the use of

standard TTL registers for data retention throughout the

system.
