DM5406J-MLS

Overview

The DM5406J-MLS is a hex inverter integrated circuit belonging to the TTL/H/L series. It features six independent single-input inverters housed in a 14-pin ceramic dual in-line package (CDIP). The device operates on a nominal 5 V supply and supports an extended temperature range from -55 °C to 125 °C. It is manufactured by National Semiconductor, now Texas Instruments, and is designed for high-reliability applications requiring standard TTL logic functionality.

Feature Summary

• Contains six independent inverting gates within a single package
• Utilizes robust ceramic packaging for environmental durability
• Supports wide operating temperature ranges suitable for harsh environments

Applications

• Military aerospace systems
• High-reliability industrial control
• Harsh environment computing

Procurement Notes

Verify the specific suffix J-MLS against official Texas Instruments documentation to confirm MIL-STD-883 screening levels and ceramic package authenticity. Ensure compatibility with existing system voltage requirements and thermal management specifications before procurement.

Selection Notes

Select this component when high reliability and radiation hardness are required. Compare pinout and electrical characteristics with other hex inverters in the DM54xx series. Confirm that the ceramic DIP package fits the mechanical constraints of the target assembly.

Part Context

This part is part of the DM54xx family of high-speed and low-power Schottky TTL logic devices. It serves as a fundamental building block for digital logic circuits requiring signal inversion. The manufacturer transitioned from National Semiconductor to Texas Instruments, maintaining continuity in product lineage and specifications.

Replacement Considerations

Check for direct equivalents such as DM5406J or DM5406J/883B from Texas Instruments. Verify functional compatibility with other hex inverters in the same logic family before substitution.
