MOTOROLA
SEMICONDUCTOR TECHNICAL DATA
9's Complementer
NBCD adder to allow BCD subtraction. A BCD number (8–4–2–1 code) is
applied to the inputs (A1 = 2 0 , A2 = 2 1 , A3 = 2 2 , A4 = 2 3 ). 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.
with the MC14560B NBCD adder, the complement control becomes an
add/subtract control.
* Maximum Ratings are those values beyond which damage to the device may occur.

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, V in and V out should be constrained
to the range V SS
appropriate logic voltage level (e.g., either V SS
or V DD ). Unused outputs must be left open.
