MC10H125MELG

Translators, Level Shifters Overview

The MC10H125MELG is a quad MECL to TTL translator manufactured by onsemi. It interfaces data and control signals between the MECL section and saturated logic sections of digital systems. The device operates within a supply voltage range of -4.94 V to -5.46 V. It features a typical propagation delay of 2.5 ns and provides voltage compensation with an improved noise margin of 150 mV over the operating voltage and temperature range. The component is housed in a 16-SOEIAJ package.

Translators, Level Shifters Feature Summary

• Provides unidirectional translation from MECL inputs to TTL outputs
• Features voltage compensated design for stable operation across temperature ranges
• Includes internal pull-downs ensuring unused outputs default to low state when inputs are open

Translators, Level Shifters Applications

• Interfacing MECL logic circuits with TTL logic circuits
• Digital system signal translation between different logic families
• Data and control signal conversion in mixed-logic environments

Translators, Level Shifters Procurement Notes

Verify the specific suffix ELG against official datasheets to confirm package type and lead-free status, as suffixes define physical attributes. Confirm availability status as this series may be discontinued or subject to production changes. Ensure compatibility with existing board layouts regarding the SOEIAJ footprint and pin configuration before procurement.

Translators, Level Shifters Selection Notes

Select this component when interfacing MECL sources with TTL destinations requiring unidirectional signal flow. It offers improved propagation delay compared to standard MECL 10K family parts without increasing power-supply current. Consider the 16-SOEIAJ package constraints and ensure the application requires the specific voltage levels and noise margins provided by this translator architecture.

Translators, Level Shifters Part Context

This part belongs to the 10H series, which serves as a functional and pinout duplication of the standard MECL 10K family. The 10H series provides a 100% improvement in propagation delay while maintaining similar power consumption characteristics. It is designed for high-speed digital applications requiring reliable translation between ECL-based and saturated logic domains.

Translators, Level Shifters Replacement Considerations

The MC10H125FN and MC10H125FNG are documented equivalents within the same product family offering identical functionality. Verify pinout compatibility and package dimensions when substituting these variants. Check for any updates in RoHS compliance or manufacturing location associated with different suffixes.
