CD74HC283E Datasheet PDF - TI

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

● Green product and no Sb/Br
