* 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).
C10 L A0 B0 A1 B1 A2 B2 A3 B3 CIN Σ0 Σ1 Σ2 Σ3 C3 COUT CIN A0 B0 A1 B1 A10 B10
A0 B0 A1 B1 A2 B2 A3 B3 CIN Σ0 Σ1 Σ2 Σ3 C.
The 74F283 adds two 4-bit binary words (An plus Bn) plus the incoming 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+2Σ.
