MOTOROLA
SEMICONDUCTOR TECHNICAL DATA
Look-Ahead Carry Block
The MC10H179 is a functional/pinout duplication of the standard MECL 10K
part, with 100% improvement in propagation delay and no increase in power
supply current.
• Power Dissipation, 300 mW Typical
• 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.
