4-Bit BCD Adder

General Description

The ’F583 high-speed 4-bit, BCD full adder with internal

Features

■ Adds two decimal numbers

carry lookahead accepts two 4-bit decimal numbers (A₀–

■ Full internal lookahead

A₃, B₀–B₃) and a Carry Input (C_n). It generates the decimal

sum outputs (S₀–S₃), and a Carry Output (C_n+4) if the sum

■ Fast ripple carry for economical expansion

■ Sum output delay time 16.5 ns max

■ Ripple carry delay time 8.5 ns max

■ Input to ripple delay time 14.0 ns max

■ Supply current 60 mA max

is greater than 9. The 'F583 is the functional equivalent of

the 82S83.
