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 V
SS
for no carry in.
