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 Switching specifications at 50 pF Switching specifications guaranteed over full temperature and VCC range Advanced oxide-isolated, ion-implanted Schottky TTL process Functionally and pin for pin compatible with LS family counterpart Improved output transient handling capability
