Overview
DM74ALS520 • DM74ALS521 8-Bit Comparator September 1986 Revised April 2000 DM74ALS520 • DM74ALS521 8-Bit Comparator General Description 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.
Features s Switching specifications at 50 pF s Switching specifications guaranteed over full temperature and VCC range s Advanced oxide-isolated, ion-implanted Schottky TTL process s Functionally and pin for pin compatible with LS family counterpart s Improved output transient handling capability Ordering Code: Ordering Code DM74ALS520WM DM74ALS520N DM74ALS521WM SM74ALS521N Package Number M20B N20A M20B N20A Package D...
