MC10125FN-G

Translators, Level Shifters Overview

The MC10125FN-G is a Quad MECL to TTL Translator manufactured by Rochester Electronics. It incorporates differential inputs and Schottky TTL totem-pole outputs for interfacing data and control signals between MECL sections and saturated logic sections of digital systems. The device features a VBB reference voltage available on pin 1 for single-ended input biasing. Outputs transition to a low logic level when inputs are left floating.

Translators, Level Shifters Feature Summary

• Provides quad translation between MECL and TTL logic families
• Incorporates differential inputs for flexible inverting or non-inverting configurations
• Features Schottky TTL totem-pole outputs
• Includes dedicated VBB reference voltage pin for single-ended input biasing

Translators, Level Shifters Applications

• Interfacing data signals between MECL and saturated logic sections
• Interfacing control signals between MECL and saturated logic sections
• Differential line receiver applications

Translators, Level Shifters Procurement Notes

Verify the manufacturer designation as Rochester Electronics, LLC, which typically handles surplus or discontinued inventory rather than original fabrication. Confirm that the suffix -G indicates lead-free compliance if required by specific assembly standards. Ensure the package type matches the LCC-20 specification found in related datasheets. Validate the revision status against current design requirements.

Translators, Level Shifters Selection Notes

Select this component when direct interface is required between MECL drivers and TTL receivers within a mixed-logic system. The differential input capability allows for noise immunity improvements over single-ended connections. The availability of a VBB pin simplifies biasing networks for single-ended operation. Verify that the output drive strength meets the load requirements of the connected TTL circuitry.

Translators, Level Shifters Part Context

This part belongs to the MC101xx series of high-speed logic devices originally designed by Motorola. Rochester Electronics continues to supply these components after their discontinuation by the primary manufacturer. The device serves as a bridge between ECL/MECL families and standard TTL logic levels.
