Two additional Select input codes force the Function outputs LOW or HIGH. An Overflow output is provided for convenience in twos complement arithmetic. A Carry output is provided for ripple expansion. For high-speed expansion using a Carry Lookahead Generator, refer to the F381 data sheet. 4-BIT ARITHMETIC LOGIC UNIT FAST SCHOTTKY TTL Performs Six Arithmetic and Logic Functions Selectable Low (Clear) and High (Preset) Functions LOW Input Loading Minimizes Drive Requirements Carry Output for Ripple Expansion Overflow Output for Twos Complement Arithmetic CONNECTION DIAGRAM VCC A2 20 19 B2 18 A3 17 B3 16 Cn Cn+4 OVR F3 15 14 13 12 F2 11 20 1 J SUFFIX CERAMIC CASE 732-03 20 1 N SUFFIX PLASTIC CASE 738-03 1 A1 2 B1 3 A0 4 B0 5 S0 6 S1 7 S2 8 F0 9 F1 10 GND 20 LOGIC SYMBOL 3 4 1 2 19 18 17 16 DW SUFFIX SOIC CASE 751D-03 1 A0 B0 A1 B1 A2 B2 A3 B3 15 7 6 5 Cn S2 S1 S0 Cn+4 OVR F0 8 F1 9 F2 11 F3 12 14 13 ORDERING INFORMATION MC54FXXXJ Ceramic MC74FXXXN Plastic MC74FXXXDW SOIC GUARANTEED OPERATING RANGES Symbol VCC TA IOH IOL Supply Voltage Operating Ambient Temperature Range 74 Output Current — High Output Current — Low 54, 74 54, 74 0 25 70 –1.0 20 Parameter 54, 74 54 Min 4.5 – 5……
