DESCRIPTION
The HCC4560B and HCF4560B are monolithic in-
tegrated circuits, available in 16-lead dual-in-line
plastic or ceramic packages and plastic micro pack-
ages.
The HCC4560B and HCF4560B add two 4-bit num-
bers in NBCD (natural binary coded decimal) for-
mat, resulting in sum and carry outputs in NBCD
code.
All inputs and outputs are active high. The carry
input for the least significant digit is connected to VSS
for no carry in.
