Figure 3. Parallel Add/Subtract Circuit
One MC14560B and MC14561B permit a
BCD digit to be added to or subtracted from
a second digit, such as in this typical config-
uration. A second MC14561B permits either
digit to be added to or subtracted from the
other, or either word to appear unmodified at
the output.
