MC10H125FNG

Translators, Level Shifters Overview

The MC10H125FNG is a quad MECL-to-TTL translator manufactured by onsemi, designed for interfacing data and control signals between the MECL section and saturated logic section of digital systems. It 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. The device operates within a supply voltage range of 4.75 V to 5.25 V and features TTL outputs. It is housed in a PLCC-28 package and supports surface-mount installation.

Translators, Level Shifters Feature Summary

• Provides signal translation from MECL inputs to TTL outputs for system interfacing
• Maintains functional and pinout compatibility with the standard MECL 10K family
• Features voltage compensated design with improved noise margin over operating ranges

Translators, Level Shifters Applications

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

Translators, Level Shifters Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels due to potential availability from secondary markets. Confirm RoHS compliance status and lead-free packaging specifications against current datasheet revisions. Check for moisture sensitivity level requirements during storage and handling. Ensure the PLCC-28 package matches board layout constraints before procurement.

Translators, Level Shifters Selection Notes

Select this component when direct interface between MECL 10K circuits and TTL logic is required without level shifting circuitry. Consider the typical 2.5 ns propagation delay for timing-sensitive designs. Verify that the 10H series power consumption meets system thermal limits compared to standard MECL 10K parts. Ensure input signals remain within specified MECL voltage levels for proper translation.

Translators, Level Shifters Part Context

This part is part of the MC10H125 series, which includes variants like MC10H125FN and MC10H125FNR2. It serves as a bridge between high-speed ECL/MECL families and standard TTL logic. The 10H designation indicates enhanced performance characteristics over the original 10K family while maintaining backward compatibility.

Translators, Level Shifters Replacement Considerations

MC10H125FN and MC10H125FNR2 are functionally equivalent variants within the same series. Standard MECL 10K family parts may serve as legacy replacements if pinout compatibility is maintained.
