74F583 - 4-bit BCD adder

General Description

The 74F583 4-bit coded (BCD) full adder performs the addition of two decimal numbers (A0 A3, B0

B3).

The look-ahead generates BCD carry terms internally, allowing the 74F583 to then do BCD addition correctly.

Key Features

  • Adds two decimal numbers.
  • Full internal look-ahead.
  • Fast ripple carry for economical expansion.
  • Sum output delay 19.5 ns max.
  • Ripple carry delay 8.5 ns max.
  • Input to ripple delay 13.0 ns max.
  • Supply current 60 mA max.

INTEGRATED CIRCUITS 74F583 4-bit BCD adder Product specification IC15 Data Handbook 1989 Apr 06 Philips Semiconductors Philips Semiconductors Product specification 4-bit BCD adder 74F583 FEATURES • Adds two decimal numbers • Full internal look-ahead • Fast ripple carry for economical expansion • Sum output delay 19.5 ns max. • Ripple carry delay 8.5 ns max. • Input to ripple delay 13.0 ns max. • Supply current 60 mA max. DESCRIPTION The 74F583 4-bit coded (BCD) full adder performs the addition of two decimal numbers (A0–A3, B0–B3). The look-ahead generates BCD carry terms internally, allowing the 74F583 to then do BCD addition correctly. For BCD numbers 0 through 9 at A and B inputs, the BCD sum forms at the output.
