INTEGRATED CIRCUITS 74F283 4-bit binary full adder with fast carry Product specification IC15 Data Handbook 1989 Mar 03 Philips Semiconductors Philips Semiconductors Product specification 4-bit binary full adder with fast carry Features - High speed 4-bit addition - Cascadable in 4-bit increments - Fast Internal carry look-ahead DESCRIPTION The 74F283 adds two 4-bit binary words (An plus Bn) plus the ining carry. The binary sum appears on the sum outputs (Σ0- Σ3) and the outgoing carry (COUT) according to the equation: CIN+20(A0+B0)+21(A1+B1)+22(A2+B2)+23(A3+B3) =Σ0+2Σ1+4Σ2+8Σ3+16COUT where (+)=plus Due to the symmetry of the binary add function, the 74F283 can be used...
