CD74HC283E

LOGIC, 4BIT BINARY FULL ADDER, 16DIP.

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.
