MC10H125PG

Translators, Level Shifters Overview

The MC10H125PG is a quad MECL-to-TTL translator manufactured by onsemi. It interfaces data and control signals between the MECL section and saturated logic section of digital systems. The device operates with a supply voltage range of 4.75 V to 5.25 V. It features a typical propagation delay of 2.5 ns and an improved noise margin of 150 mV over the operating voltage and temperature range. The component is housed in a 16-pin PDIP package.

Translators, Level Shifters Feature Summary

• Translates signals from MECL levels to TTL levels for system interfacing
• Provides voltage compensation for stable operation across temperature ranges
• Maintains compatibility with standard MECL 10K family pinouts

Translators, Level Shifters Applications

• Interfacing MECL sections with saturated logic sections in digital systems
• Data and control signal translation between different logic families
• Bus driver applications requiring MECL to TTL conversion

Translators, Level Shifters Procurement Notes

Verify the specific suffix PG indicates a plastic DIP package configuration. Confirm RoHS compliance status as older revisions may differ. Check current lifecycle status as this series has faced obsolescence notices. Ensure the supplier provides official datasheets matching the exact part number revision for accurate electrical parameter verification before procurement.

Translators, Level Shifters Selection Notes

Select this component when direct interface between MECL and TTL logic is required without external level shifting circuitry. Consider the 2.5 ns propagation delay for timing constraints. Verify that the 16-pin PDIP package fits the target PCB layout. Compare against the MC10H125FN variant if surface mount packaging is preferred instead of through-hole installation.

Translators, Level Shifters Part Context

This part belongs to the MC10H125 family of quad MECL-to-TTL translators. It serves as a functional and pinout duplication of the standard MECL 10K family part, offering improved propagation delay without increasing power-supply current. The device ensures reliable signal translation in mixed-logic environments.

Translators, Level Shifters Replacement Considerations

The MC10H125FN is a verified surface-mount replacement option within the same family. The MC10H125FNG offers a lead-free version of the PLCC package. Direct pin-compatible substitutes include the legacy Motorola MC10125.
