MC10H166FN

Comparators Overview

The MC10H166FN is a 5-bit magnitude comparator from onsemi's MC10H series, designed for high-speed digital logic applications. It operates within a supply voltage range of -4.2V to -5.5V and features a propagation delay of 1.4ns at 5V. The device provides high-active outputs indicating A<B, A=B, and A>B relationships. It is housed in a 20-PLCC package with J-leads, suitable for surface mount installation. The component supports differential inputs and outputs, ensuring robust signal integrity in demanding environments.

Comparators Feature Summary

• Provides simultaneous comparison results for less than, equal to, and greater than conditions
• Features high-active output signals for clear logic state indication
• Utilizes differential input and output architecture for noise immunity
• Offers functional compatibility with standard MECL 10K parts

Comparators Applications

• High-speed digital data processing systems
• Address decoding and comparison circuits
• Threshold detection in analog-to-digital conversion interfaces
• Computer arithmetic logic units requiring fast magnitude evaluation

Comparators Procurement Notes

Verify the specific suffix 'FN' corresponds to the 20-pin PLCC package configuration. Confirm that the -5V ECL power supply requirements align with your system design. Check for RoHS compliance status as older MC10H series parts may not meet current environmental standards. Ensure thermal management considerations are addressed for the plastic leaded chip carrier package during operation.

Comparators Selection Notes

Select this component when a 5-bit magnitude comparison function is required with ECL speed performance. Consider the 20-PLCC package constraints for PCB layout and socket availability. Evaluate the need for differential signaling capabilities versus single-ended alternatives. Verify that the operating temperature range of 0°C to 75°C meets your application's environmental specifications.

Comparators Part Context

This part belongs to onsemi's MC10H family, which represents an enhanced version of the classic MECL 10K logic series. The MC10H series offers improved performance characteristics while maintaining pinout compatibility with legacy designs. This specific comparator integrates five bits of comparison logic into a single compact integrated circuit, serving as a bridge between traditional ECL speeds and modern packaging requirements.

Comparators Replacement Considerations

The MC10E166FN is a related 9-bit comparator from the same manufacturer but differs in bit width and package type. Direct pin-compatible replacements should be verified against official substitution lists. Legacy MECL 10K equivalents may require level shifting or power supply adjustments due to voltage differences.
