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).

S3), and a Carry Output (Cn+4) if the sum is greater than 9.

74F583 4-Bit BCD Adder April 1988 Revised March 1999 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.
