SEMICONDUCTOR TECHNICAL DATA
The MC10H166 is a 5–Bit Magnitude Comparator and is a functional/
pinout duplication of the standard MECL 10K part with 100%
improvement in propagation delay and no increase in power–supply
current.
The MC10H166 is a high–speed expandable 5–bit comparator for
comparing the magnitude of two binary words. Two outputs are provided:
A<B and A>B. The A = B function can be obtained by wire–ORing these
outputs (a low level indicates A = B) or by wire–NORing the outputs (a
high level indicates A = B). A high level on the enable function forces both
outputs low.
• Propagation Delay, Data–to–Output, 2.0 ns Typical
• Power Dissipation 440 mW Typical
• Improved Noise Margin 150 mV (Over Operating Voltage and
Temperature Range)
• Voltage Compensated
• MECL 10K–Compatible

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.

For longer word lengths, the MC10H166 can be serially
expanded or cascaded. Figure 1 shows two devices in a
serial expansion for a 9–bit word length. The A > B and
A < B outputs are fed to the A0 and B0 inputs respectively
