SEMICONDUCTOR TECHNICAL DATA
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.

NOTES:
Each MECL 10H series circuit has been designed to meet the dc specifications shown in the test table,
after thermal equilibrium has been established. The circuit is in a test socket or mounted on a printed circuit
board and transverse air flow greater than 500 Ifpm is maintained. Outputs are terminated through a
50–ohm resistor to –2.0 volts.
Pin assignment is for Dual–in–Line Package.
For PLCC pin assignment, see the Pin Conversion
Tables on page 6–11 of the Motorola MECL Data
Book (DL122/D).
