No Preview Available ! 8-BIT IDENTITY COMPARATOR The MC54/74F521 is an expandable 8-bit comparator. It compares two words of up to eight bits each and provides a LOW output when the two words match bit for bit. The expansion input IA = B also serves as an active-LOW en- able input. • Compares Two 8-Bit Words in 6.5 ns Typical • Expandable to Any Word Length • 20-Pin Package CONNECTION DIAGRAM (TOP VIEW) VCC OA = B B7 A7 B6 A6 B5 A5 B4 20 19 18 17 16 15 14 13 12 A4 11 MC54/74F521 8-BIT IDENTITY COMPARATOR FAST™ SCHOTTKY TTL 20 1 J SUFFIX CERAMIC CASE 732-03 1 2 3 4 5 6 7 8 9 10 IA = B A0 B0 A1 B1 A2 B2 A3 B3 GND GUARANTEED OPERATING RANGES Symbol Parameter VCC TA Supply Voltage Operating Ambient Temperature Range IOH Output Current  High IOL Output Current  Low 54, 74 54 74 54,74 54, 74 20 1 N SUFFIX PLASTIC CASE 738-03 20 1 DW SUFFIX SOIC CASE 751D-03 ORDERING INFORMATION MC54FXXXJ Ceramic MC74FXXXN Plastic MC74FXXXDW SOIC Min Typ Max Unit 4.5 5.0 5.5 V –55 25 125 °C 0 25 70 –1.0 mA 20 mA FAST AND LS TTL DATA 4-195 1 page
