SEMICONDUCTOR TECHNICAL DATA
The MC10H181 is a high–speed arithmetic logic unit capable of performing
16 logic operations and 16 arithmetic operations on two four–bit words. Full
internal carry is incorporated for ripple through operation.
Arithmetic logic operations are selected by applying the appropriate binary
word to the select inputs (S0 through S3) as indicated in the tables of
arithmetic/logic functions. Group carry propagate (PG) and carry generate (GG)
are provided to allow fast operations on very long words using a second order
look–ahead. The internal carry is enabled by applying a low level voltage to the
mode control input (M).
When used with the MC10H179, full–carry look–ahead, as a second order
look–ahead block, the MC10H181 provides high–speed arithmetic operations
on very long words.
This 10H part is a functional/pinout duplication of the standard MECL 10K
family part with 100% improvement in propagation delay and no increase in
power supply current.
• Improved Noise Margin, 150 mV (Over Operating Voltage and
Temperature Range)
• Voltage Compensated • MECL 10K – Compatible

NOTE:
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.
