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.
