CD54HC283, CD74HC283, CD54HCT283, CD74HCT283 Data sheet acquired from Harris Semiconductor SCHS176D November 1997 - Revised October 2003 High-Speed CMOS Logic 4-Bit Binary Full Adder with Fast Carry Description The ’HC283 and ’HCT283 binary full adders add two 4-bit binary numbers and generate a carry-out bit if the sum exceeds 15. 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.
