MC10E166FN

Comparators Overview

The MC10E166FN is a 9-bit magnitude comparator from the onsemi 10E series, designed for ECL logic applications. It operates within a supply voltage range of 4.2V to 5.5V or -4.2V to -5.5V. The device features active high outputs indicating A<B, A=B, and A>B relationships. It provides high output current drive capabilities of 50mA for both high and low states. The typical propagation delay is 1.4ns at 5V. It is housed in a 28-PLCC package with dimensions of 11.51x11.51mm and supports surface mount installation.

Comparators Feature Summary

• Provides three distinct active high outputs to indicate comparison results between two 9-bit inputs.

Comparators Applications

• High-speed digital data processing systems requiring magnitude comparison.

Comparators Procurement Notes

Verify component authenticity through authorized distributors or certified secondary market suppliers like Rochester Electronics. Confirm RoHS compliance status as the standard FN variant may not meet current environmental regulations. Check for lead-free alternatives if required by specific manufacturing standards. Ensure proper handling due to ECL sensitivity and static discharge precautions during storage and assembly.

Comparators Selection Notes

Select this component when a dedicated 9-bit magnitude comparator with ECL compatibility is required. Consider the 1.4ns propagation delay for timing-critical high-speed designs. Evaluate the 28-PLCC package constraints against PCB layout requirements. Verify power supply stability within the specified 4.2V to 5.5V range to ensure correct logical operation and signal integrity.

Comparators Part Context

Part of the onsemi 10E series, which focuses on high-speed ECL logic functions. This series includes various comparators and drivers optimized for fast switching speeds. The MC10E166FN specifically addresses the need for multi-bit comparison in legacy or specialized high-frequency electronic systems where ECL signaling remains relevant.

Comparators Replacement Considerations

Check for MC10E166FNG as a potential lead-free alternative. Verify pinout and electrical specifications match before substitution. Consult official replacement guides for discontinued parts.
