The MC10H180 is a highspeed, lowpower, generalpurpose adder/ subtractor. It is designed to be used in special purpose adders/subtractors or in highspeed multiplier arrays. Inputs for each adder are Carryin, Operand A, and Operand B; outputs are Sum, Sum and Carryout. 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 Typicalh180 Improved Noise Margin 150 mV (Over Operating Voltage and Temperature Range)
