DM74S157 • DM74S158 Quad 1 of 2 Line Data Selector/Multiplexer
August 1986
Revised April 2000
DM74S157 • DM74S158
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 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.
Applications
• Expand any data input point
• Multiplex dual data buses
• Generate four functions of two variables (one variable is
common)
• Source programmable counters
