MC10H125MG

Translators, Level Shifters Overview

The MC10H125MG 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 while providing improved propagation delay without increasing power-supply current. It operates within a supply voltage range of 4.75 V to 5.25 V and features a typical propagation delay of 2.5 ns. The component is housed in a 16-pin SOIC package and supports surface mount installation.

Translators, Level Shifters Feature Summary

• Provides voltage level translation between MECL and TTL logic families
• Offers improved noise margin over operating voltage and temperature ranges
• Ensures outputs default to low state when inputs are left open

Translators, Level Shifters Applications

• Interfacing data signals between MECL and saturated logic sections
• Connecting control signals across different logic voltage domains
• Bus driver applications requiring MECL to TTL conversion

Translators, Level Shifters Procurement Notes

Verify the specific suffix 'MG' against official manufacturer documentation to confirm exact packaging and compliance details. Confirm availability status as older 10H series components may have limited stock or obsolescence notices. Ensure the required operating temperature range and supply voltage specifications align with system requirements before procurement.

Translators, Level Shifters Selection Notes

Select this component when interfacing MECL 10K compatible circuits with TTL logic. It provides a direct pinout replacement for standard MECL translators with enhanced speed. Consider the 16-pin SOIC package constraints and ensure adequate thermal management for the specified operating temperature range.

Translators, Level Shifters Part Context

The MC10H125MG belongs to the onsemi 10H logic series, which maintains compatibility with the legacy MECL 10K family. This series is designed for high-speed digital systems requiring reliable voltage translation. The device serves as a bridge between differential MECL signaling and single-ended TTL logic levels.

Translators, Level Shifters Replacement Considerations

The MC10H125FN and MC10H125FNG are documented variants of the same quad MECL-to-TTL translator function. Verify package compatibility and lead-free status when substituting.
