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.
