MC14560B NBCD Adder
The MC14560B adds two 4bit numbers in NBCD (natural binary coded decimal) format, resulting in sum and carry outputs in NBCD code. This device can also subtract when one set of inputs is complemented with a 9's Complementer (MC14561B). A ll inputs and outputs are active high. The carry input for the least significant digit is connected to VSS for no carry in. · Diode Protection on All Inputs · Supply Voltage Range = 3.0 Vdc to 18 Vdc · Capable of Driving Two Lowpower TTL Loads or One Lowpower Schottky TTL Load Over the Rated Temperature Range MAXIMUM RATINGS* (Voltages Referenced to VSS)

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