Quad 2-to-1 Line Data Selector/Multiplexer (Inverting)
DM74LS157 • DM74LS158 Quad 2-Line to 1-Line Data Selectors/Multiplexers September 1986 Revised April 2000 DM74LS157 • DM74LS158 Quad 2-Line to 1-Line Data Selectors/Multiplexers General Description Applications These data selectors/multiplexers contain inverters and • Expand any data input point drivers to supply full on-chip data selection to the four out- • Multiplex dual data buses put gates. A separate strobe input is provided. A 4-bit word • Generate four functions of two variables is selected from one of two sources and is routed to the (one variable is common) four outputs. The DM74LS157 presents true data whereas • Source programmable counters the DM74LS158 presents inverted data to minimize propa- gation delay time.
