Quad 1 of 2 Line Data Selector/Multiplexer

General Description

Applications

These data selectors/multiplexers contain inverters and

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

put gates. A separate strobe input is provided. A 4-bit word

is selected from one of two sources and is routed to the

four outputs. The DM74S157 presents true data whereas

the DM74S158 presents inverted data to minimize propa-

gation delay time.

•

Expand any data input point

Multiplex dual data buses

Generate four functions of two variables (one variable is

common)

•

Source programmable counters

Features
