MC14561B Datasheet | Motorola Semiconductor

MOTOROLA SEMICONDUCTOR TECHNICAL DATA MC14561B 9's plementer The MC14561B 9’s plementer is a panion 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 plement control (p) is low, the BCD number appears at the outputs unmodified. The plement disable (p) allows the plement control to be gated, or an inverted control signal to be used. If the plement input is high and the disable input low, the 9’s plement 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 plement control bees an add/subtract control.
