MC10H125L

Translators, Level Shifters Overview

The MC10H125L is a quad MECL-to-TTL translator manufactured by onsemi. It interfaces data and control signals between MECL sections 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. Key electrical characteristics 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 signal translation between MECL and TTL logic levels
• Features voltage compensation for stable operation across ranges
• Ensures high noise immunity with improved margins
• Maintains compatibility with standard MECL 10K pinouts

Translators, Level Shifters Applications

• Interfacing MECL sections with saturated logic in digital systems
• Translating data signals between different logic families
• Control signal conversion in mixed-logic environments

Translators, Level Shifters Procurement Notes

Verify the specific suffix 'L' against official datasheets to confirm package type and material composition. Confirm RoHS compliance status as availability varies by production batch. Check for obsolete status or end-of-life notifications from the manufacturer before procurement planning.

Translators, Level Shifters Selection Notes

Select this component when direct interfacing between MECL and TTL circuits is required without external level-shifting components. Ensure system power supplies support the specific voltage requirements of the 10H series. Consider the 2.5 ns propagation delay for timing-critical applications within the design constraints.

Translators, Level Shifters Part Context

This part belongs to the MC10H100 series of high-speed ECL-compatible logic devices. It serves as a bridge between the fast MECL signaling standards and standard TTL logic levels. The device maintains the performance benefits of the 10H series while providing necessary protocol conversion for system integration.

Translators, Level Shifters Replacement Considerations

The MC10H125FN and MC10H125FNG are documented equivalents within the same product family. Verify pinout compatibility and package dimensions before substituting. Cross-reference with Motorola MC10125 specifications for legacy system replacements.
