SEMICONDUCTOR TECHNICAL DATA
5-Bit Magnitude Comparator
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

Pin assignment is for Dual±in±Line Package. For PLCC pin assignment, see the Pin Conversion Tables on page 6±36 of the Motorola MECL Data Book (DL122/D).
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 9±Bit Word
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
of the next device. The connection for an A = B output is also shown. The worst case delay time of serial expansion is equal to the number of comparators times the data±to±output delay.
