100324W-QMLV

Overview

The National Semiconductor 100324W-QMLV is a qualified mixed-signal level translator designed for aerospace and defense applications. It functions as a unidirectional converter, translating TTL input signals to ECL output signals. The device integrates six channels within a single circuit configuration, providing differential outputs for high-speed signal integrity. Manufactured under the QMLV qualification standard, it ensures reliability in harsh environments with an operating temperature range of -55°C to +125°C. The component utilizes a 28-PLCC package, offering a compact footprint suitable for space-constrained systems requiring robust voltage level shifting between logic families.

Feature Summary

• Unidirectional translation from TTL inputs to ECL outputs
• Six-channel differential output capability
• Qualified for military/aerospace environments (QMLV)
• Wide operating temperature range

Applications

• Aerospace communication systems
• Military avionics interfaces
• Defense electronics requiring TTL-to-ECL conversion
• Harsh environment data acquisition systems

Procurement Notes

Verify that the specific suffix 'W-QMLV' corresponds to the exact radiation hardness and temperature grade required for your mission profile. Confirm package authenticity and traceability documentation upon receipt. Ensure compatibility with existing TTL drivers and ECL receivers in the target design. Check for any updated revision notices from Texas Instruments regarding legacy National Semiconductor components.

Selection Notes

Select this component when a qualified, unidirectional TTL-to-ECL translator is required for critical systems. The six-channel density reduces board space compared to discrete solutions. Verify that the ECL load requirements match the driver capabilities of the 100324W-QMLV. Consider the 28-PLCC package constraints during PCB layout planning.

Part Context

This part belongs to the National Semiconductor 100324 series of mixed-signal level translators. While similar parts like the 100324QI exist, they may differ in qualification status or packaging. The 100324W-QMLV specifically denotes the wide temperature and QMLV qualified variant. Understanding the distinction between commercial and qualified versions is essential for procurement accuracy.

Replacement Considerations

Direct replacements must maintain QMLV qualification and TTL-to-ECL functionality. Verify pinout compatibility with the 28-PLCC package. Consult Texas Instruments documentation for any approved alternates that meet the same environmental and electrical specifications.
