Dual 2−Bit Adder/Subtractor

The MC10H180 is a high–speed, low–power, general–purpose adder/subtractor. It is designed to be used in special purpose adders/subtractors or in high–speed multiplier arrays.
Inputs for each adder are Carry–in, Operand A, and Operand B; outputs are Sum, Sum and Carry–out. The common select inputs serve as a control line to Invert A for subtract, and a control line to Invert B.

• Propagation Delay, 1.8 ns Typical, Operand and Select to Output
• Power Dissipation, 360 mW Typical
• Improved Noise Margin 150 mV (Over Operating Voltage and Temperature Range)
• Voltage Compensated
• MECL 10K–Compatible
