MC10124L

Translators, Level Shifters Overview

The MC10124L is a Quad TTL-to-MECL translator manufactured by onsemi. It belongs to the 10K series of ECL logic devices and features four independent translation circuits within a single package. The component converts TTL logic levels to MECL signal standards, facilitating interface between different logic families. It utilizes a plastic LCC-20 surface-mount package for integration into high-density circuit boards.

Translators, Level Shifters Feature Summary

• Provides quad translation from TTL input levels to MECL output signals
• Designed for compatibility with standard ECL logic families
• Utilizes a compact plastic leaded chip carrier package

Translators, Level Shifters Applications

• Interface circuits connecting TTL-based systems to ECL backplanes
• Signal level conversion in mixed-logic data processing units
• High-speed digital communication interfaces requiring MECL signaling

Translators, Level Shifters Procurement Notes

Verify the specific suffix 'L' against the manufacturer's official datasheet to confirm package type and material composition. Ensure the device meets required environmental compliance standards for the target application. Confirm availability status as older ECL components may have limited production runs or obsolescence risks.

Translators, Level Shifters Selection Notes

Select this component when a direct interface between TTL inputs and MECL outputs is required without external buffering. Consider the 10K series speed characteristics relative to system timing requirements. Evaluate the LCC-20 package suitability for the available PCB real estate and thermal management constraints.

Translators, Level Shifters Part Context

This part is part of the broader 10K ECL family, which includes various gates, drivers, and translators. It serves as a bridge component, allowing legacy TTL designs to interact with faster MECL-based architectures. Similar parts in the family include the MC10125 for MECL-to-TTL translation.

Translators, Level Shifters Replacement Considerations

The MC10124P is a documented equivalent variant offering identical quad TTL-to-MECL translation functionality. Verify pinout compatibility and package dimensions before substitution.
