FEATURES
DESCRIPTION
The 74F283 adds two 4-bit binary words (An plus Bn) plus the
incoming carry. The binary sum appears on the sum outputs
( 0– 3) and the outgoing carry (C
C
= 0+2 1+4 2+8 3+16C
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 1– 4 and C
should be interpreted also as active-Low. With active-High inputs,
C
intended. Interchanging inputs of equal weight does not affect the
operation, thus A0, B0, C
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.
