MC10124FN

Translators, Level Shifters Overview

The MC10124FN 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. The component utilizes a 20-PLCC (9x9) surface-mount package with J-leads. It operates within an industrial temperature range of 0°C to 75°C. The device provides differential outputs suitable for high-speed digital signal translation between TTL and MECL logic families.

Translators, Level Shifters Feature Summary

• Translates TTL input signals to MECL output levels
• Contains four independent translation channels
• Supports surface mount mounting via PLCC package

Translators, Level Shifters Procurement Notes

Verify current availability status as the part may be obsolete or subject to end-of-life notices. Confirm RoHS compliance requirements against specific project standards, noting that older 10K series variants often lack lead-free certification. Ensure the 20-PLCC package footprint matches the PCB design constraints before finalizing procurement orders.

Translators, Level Shifters Selection Notes

Select this component when interfacing legacy TTL logic with MECL-compatible high-speed circuits. Verify that the system power supply supports the required negative voltage rails typical for ECL operation. Consider thermal management requirements associated with the plastic PLCC package during continuous high-frequency switching operations.
