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.
In addition of two BCD numbers totalling a number greater than 9, a
valid BCD number and carry will result. For input values larger than
9, the number is converted from binary to BCD. Binary to BCD
conversion occurs by grounding one set of inputs, An or Bn, and
applying a 4-bit binary number to the other set of inputs. If the input
is between 0 and 9, a BCD number occurs at the output. If the
binary input falls between 10 and 15, a carry term is generated. Both
the carry term and the sum are the BCD equivalent of the binary
input. Converting binary numbers greater than 16 may be achieved
by cascading 74F583s.
