The CD74HC283E is a CMOS logic high-speed 4-bit binary Full Adder with fast-carry. Because of the symmetry of the add function, this device can be used with either all active-high operands (positive logic) or with all active-low operands (negative logic). When using positive logic the carry-in input must be tied low if there is no carry-in.
Adds two binary numbers
Full internal look ahead
Fast ripple carry for economical expansion
Operates with both positive and negative logic
Balanced propagation delay and transition times
Significant power reduction compared to LSTTL logic ICs
