MC14561B
The MC14561B 9’s complementer is a companion to the MC14560B
NBCD adder to allow BCD subtraction. A BCD number (8–4–2–1 code) is
applied to the inputs (A1 = 20, A2 = 21, A3 = 22, A4 = 23). If the complement
control (Comp) is low, the BCD number appears at the outputs unmodified.
The complement disable (Comp) allows the complement control to be gated,
or an inverted control signal to be used. If the complement input is high and
the disable input low, the 9’s complement of the number is displayed at the
outputs. The zero control (Z), when high, forces the outputs low regardless of
the state of the other inputs.
When the MC14561B is used to perform BCD subtraction in conjunction
with the MC14560B NBCD adder, the complement control becomes an
add/subtract control.

This device contains protection circuitry to
guard against damage due to high static
voltages or electric fields. However, pre-
cautions must be taken to avoid applications of
any voltage higher than maximum rated volt-
ages to this high–impedance circuit. For proper
operation, Vin and Vout should be constrained
to the range VSS
(Vin or Vout)
Unused inputs must always be tied to an
appropriate logic voltage level (e.g., either VSS
or VDD). Unused outputs must be left open.
