MC10H125MEL

Translators, Level Shifters Overview

The MC10H125MEL 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 belongs to the 10H series, offering functional and pinout compatibility with the standard MECL 10K family. It provides a typical propagation delay of 2.5 ns without increasing power-supply current compared to its predecessor.

Translators, Level Shifters Feature Summary

• Provides voltage compensated translation between MECL and TTL logic levels
• Features improved noise margin of 150 mV over operating voltage and temperature range
• Outputs default to low state when inputs are left open

Translators, Level Shifters Applications

• Interfacing data signals between MECL and saturated logic sections
• Translating control signals in mixed-logic digital systems
• MECL 10K compatible system upgrades

Translators, Level Shifters Procurement Notes

Verify RoHS compliance status as packages may vary between lead-free and non-compliant versions. Confirm package suffix 'MEL' corresponds to SOIC-16 specifications. Check for obsolescence notices or PCN documentation regarding manufacturing changes. Ensure supply chain sources provide original manufacturer datasheets for accurate electrical parameter validation.

Translators, Level Shifters Selection Notes

Select this component for applications requiring direct replacement of standard MECL 10K translators with improved speed. The 10H series maintains identical pinouts while reducing propagation delay. Verify that the target system operates within the specified voltage ranges for both MECL and TTL sections. Consider unused input handling requirements where open inputs result in low output states.

Translators, Level Shifters Part Context

This part belongs to the MC10H125 family of quad MECL-to-TTL translators. Variants include MC10H125FN and MC10H125FNG, differing primarily in packaging and environmental compliance. The 10H designation indicates enhanced performance characteristics relative to the legacy 10K series while maintaining backward compatibility.

Translators, Level Shifters Replacement Considerations

MC10125 serves as the legacy equivalent from Motorola. Direct substitution requires verifying voltage level compatibility and ensuring the target application supports the specific output behavior of open inputs resulting in low states.
