Product specification
74F283
4-bit binary full adder with fast carry
2
1989 Mar 03
853-0364 95944
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
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+2Σ1+4Σ2+8Σ3+16COUT
where (+)=plus
Due to the symmetry of the binary add function, the 74F283 can be
used with either all active-High operands (positive logic) or with all
active-Low operands (negative logic). See Function Table. In case of
all active-Low operands (negative logic) the results
Σ1–Σ4 and COUT
should be interpreted also as active-Low. With active-High inputs,
CIN cannot be left open; it must be held Low when no “carry in” is
intended. Interchanging inputs of equal weight does not affect the
operation, thus A0, B0, CIN can arbitrarily be assigned to pins 5, 6,
7, etc.
Due to pin limitations, the intermediate carries of the 74F283 are not
brought out for use as inputs or outputs. However, other means can
be used to effectively insert a carry into, or bring a carry out from, an
intermediate stage.
