4-bit full adder with fast carry 74HC/HCT583
FEATURES
• Adds two decimal numbers
• Full internal look-ahead
• Fast ripple carry for economical expansion
• Output capability: standard driver
• ICC category: MSI
The “583” generates the decimal sum outputs (∑
and a carry output (C
If an addition of two BCD numbers produce a number
greater than 9, a valid BCD number and a 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.
GENERAL DESCRIPTION
The 74HC/HCT583 are high-speed Si-gate CMOS devices
and are pin compatible with low power Schottky TTL
(LSTTL). They are specified in compliance with JECEC
standard no. 7A.
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 “583s”.
See the “283” for the binary version.
The 74HC/HCT583 are high-speed 4-bit BCD full adders
with internal carry look-ahead. They accept two 4-bit
decimal numbers (A
to A3 and B0 to B3) and a carry input
0
(CIN).
