DM74ALS520, 8-Bit Comparator

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 outp
