MC10H125M

Translators, Level Shifters Overview

The MC10H125M 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 family, offering functional and pinout compatibility with the standard MECL 10K family. Key electrical parameters include a typical propagation delay of 2.5 ns and an improved noise margin of 150 mV over the operating voltage and temperature range. Outputs default to a low state when inputs are left open.

Translators, Level Shifters Feature Summary

• Provides voltage level translation between MECL and TTL logic families
• Features voltage compensated operation for stability across ranges
• Ensures improved noise margin under varying conditions

Translators, Level Shifters Applications

• Interfacing data signals between MECL and saturated logic sections
• Connecting control signals in mixed-logic digital systems
• Bus driving applications requiring MECL to TTL conversion

Translators, Level Shifters Procurement Notes

Verify the specific suffix against official documentation to confirm package type and lead-free status. Confirm current availability as older 10H series components may have limited stock or obsolescence notices. Ensure the selected variant matches the required interface voltage levels and packaging constraints for the target design.

Translators, Level Shifters Selection Notes

Select this component when interfacing MECL 10K compatible circuits with TTL logic. It serves as a direct replacement for standard MECL translators with enhanced speed. Consider the 2.5 ns propagation delay for timing-critical paths. Verify that the 150 mV noise margin meets system requirements for the specific operating environment.

Translators, Level Shifters Part Context

The MC10H125M is part of the 10H logic family from onsemi. This family maintains compatibility with the legacy MECL 10K standard while providing performance improvements. It is designed for high-speed digital applications requiring reliable signal translation between different logic voltage domains without increasing power consumption.

Translators, Level Shifters Replacement Considerations

The MC10H125 is functionally equivalent to the MC10125. Check datasheets for specific suffix variations regarding package style and environmental compliance.
