74F283 4-bit binary full adder with fast carry
Product specification IC15 Data Handbook 1989
Product specification
4-bit binary full adder with fast carry
74F283
FEATURES
High speed 4-bit addition Cascadable 4-bit increments Fast Internal carry look-ahead
DESCRIPTION
74F283 adds 4-bit binary words plus plus incoming carry. binary appears outputs (0-3) outgoing carry (COUT) according equation: =0+21+42+83+16COUT where (+)=plus symmetry binary function, 74F283 used with either active-High operands (positive logic) with active-Low operands (negative logic). Function Table. case active-Low operands (negative logic) results COUT should interpreted also active-Low. With active-High inputs, cannot left open; must held when "carry intended. Interchanging inputs equal weight does affect operation, thus arbitrarily assigned pins etc. limitations, intermediate carries 74F283 brought inputs outputs. However, other means used effectively insert carry into, bring carry from, intermediate stage.

Figure shows make 3-bit adder. Tying operand inputs fourth adder (A3, makes dependent only equal carry from third adder. Using somewhat same principle, Figure shows dividing 74F283 into 2-bit 1-bit adder. third stage adder (A2, used means getting carry (C10) signal into fourth stage adder (via bringing carry from second stage Note that long same, whether High Low,
they influence Similarly, when same, carry into third stage does influence carry third stage. Figure shows method implementing 5-input encoder where inputs equally weighted. outputs present binary number inputs I0-I4 that true. Figure shows method implementing 5-input majority gate. When three more inputs I0-I4 true, output true.
