1 / 5 page © 2000 Fairchild Semiconductor Corporation DS006470 www.fairchildsemi.com 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 Features s Buffered inputs and outputs s Typical propagation time DM74S157 5 ns DM74S158 4 ns s Typical power dissipation DM74S157 250 mW DM74S158 195 mW Ordering Code: Connection Diagrams DM74S157 DM74S158 Order Number Package Number Package Description DM74S157N N16E 16-Lead Plastic Dual-In-Line Package (PDIP), JEDEC MS-001, 0.300 Wide DM74S158N N16E 16-Lead Plastic Dual-In-Line Package (PDIP), JEDEC MS-001, 0.300 Wide |
