| DM74ALS520 • DM74ALS521 8-Bit Comparator DM74ALS520 • DM74ALS521 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 outputs for wire AND cascading. Additionally, the DM74ALS520 is provided with B input pull up termination resistors for analog or switch data. s Switching specifications at 50 pF s Switching specifications guaranteed over full tempera- ture 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 Package Number Package Description DM74ALS520WM M20B 20-Lead Small Outline Integrated Circuit SOIC , JEDEC MS-013, Wide DM74ALS520N N20A 20-Lead Plastic Dual-In-Line Package PDIP , JEDEC MS-001, Wide DM74ALS521WM M20B 20-Lead Small Outline Integrated Circuit SOIC , JEDEC MS-013, Wide SM74ALS521N N20A 20-Lead Plastic Dual-In-Line Package PDIP , JEDEC MS-001, Wide Devices also available in Tape and Reel.

The device should not be operated at these limits. The parametric values defined in the Electrical Characteristics tables are not guaranteed at the absolute maximum ratings. The “Recommended Operating Conditions” table will define the conditions for actual device operation. Recommended Operating Conditions VCC VIH VIL IOH IOL TA Parameter Supply Voltage HIGH Level Input Voltage LOW Level Input Voltage HIGH Level Output Current LOW Level Output Current Free Air Operating Temperature Units Electrical Characteristics over recommended operating free air temperature range. All typical values are measured at VCC = 5V, TA = 25°C.
