Partname: | SM74ALS521N |
Description: | 8-Bit Comparator |
Manufacturer: | Fairchild Semiconductor |
Datasheet: | PDF (51.4K). Click here to download *) |
These comparators perform an "equal to" comparison of two 8-bit words with provision for expansion or external enabling. The matching of the two 8-bit input plus a logic LOW on the EN input produces the output A = B on the DM74ALS520 and DM74ALS521. The DM74ALS520 and DM74ALS521 have totem pole outputs for wire AND cascading. Additionally, the DM74ALS520 is provided with B input pull up termination resistors for analog or switch data. |
