Partname: | DM74ALS257SJ |
Description: | 3-STATE Quad 1-of-2 Line Data Selector/Multiplexer |
Manufacturer: | Fairchild Semiconductor |
Package: | SOIC |
Pins: | 16 |

These data selectors/multiplexers contain inverters and drivers to supply full on-chip data selection to the four 3STATE 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 propagation delay time. |
