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. Product Highlights: 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
