74F583
4-Bit BCD Adder
General Description
The ’F583 high-speed 4-bit, BCD full adder with internal
carry lookahead accepts two 4-bit decimal numbers (A0–
A3, B0–B3) and a Carry Input (Cn). It generates the decimal
sum outputs (S0–S3), and a Carry Output (Cn+4) if the sum
is greater than 9. The 'F583 is the functional equivalent of
the 82S83.
Features
s Adds two decimal numbers
s Full internal lookahead
s Fast ripple carry for economical expansion
s Sum output delay time 16.5 ns max
s Ripple carry delay time 8.5 ns max
s Input to ripple delay time 14.0 ns max
s Supply current 60 mA max
