JM54AC151S2A-RH

Overview

The JM54AC151S2A-RH is a high-speed CMOS 8-channel multiplexer designed for aerospace applications. It operates within a voltage range of 2 V to 6 V and features hermetic ceramic packaging. The component provides radiation hardness against total ionizing dose up to 300 krad (Si) and immunity to single event latch-up up to 110 MeV.cm²/mg. It supports an extended temperature range from -55 °C to +125 °C and holds QML-V qualification.

Feature Summary

• High radiation hardness suitable for demanding space conditions
• Immunity to single event latch-up and upset events
• Hermetic ceramic housing for environmental protection

Applications

• Aerospace systems requiring radiation tolerance
• Harsh environment signal routing
• Military electronic equipment

Procurement Notes

Verify the specific suffix 'RH' against official manufacturer documentation to confirm radiation hardening status and package type. Ensure the part number matches the exact QML-V qualified listing on the Defense Logistics Agency website, as suffixes may indicate variations in testing or screening levels not covered by general datasheets.

Selection Notes

Select this component when radiation tolerance and hermetic sealing are mandatory requirements. It is appropriate for designs operating between 2 V and 6 V that require high-speed CMOS logic performance in extreme thermal environments. Verify compatibility with existing control signals and power supply constraints before integration.

Part Context

This device belongs to the 54AC/54ACT series of high-speed CMOS functions manufactured by National Semiconductor, now part of Texas Instruments. The series includes various logic gates, flip-flops, and multiplexers specifically engineered to meet strict aerospace industry standards for reliability and environmental resilience.

Replacement Considerations

Consult the DLA Standard Microcircuit Drawing database for approved equivalents. Potential substitutes include other QML-V qualified 8-channel multiplexers from the same family, provided they match the radiation hardness and hermetic package specifications.
