JM54AC151SFA-RH

Overview

The JM54AC151SFA-RH is a high-speed CMOS 8-channel multiplexer from the 54AC series, designed for aerospace and harsh environments. It features hermetic ceramic packaging and radiation hardness qualification. The device operates within a voltage range of 2 V to 6 V and withstands total ionizing doses up to 300 krad (Si). It is immune to single event latch-up up to 110 MeV.cm²/mg and functions across a temperature range of -55 °C to +125 °C.

Feature Summary

• Radiation-hardened design with immunity to single event latch-up and upset
• Hermetic ceramic package construction suitable for extreme conditions
• High-speed CMOS logic technology optimized for aerospace applications

Applications

• Aerospace satellite systems
• Spacecraft data routing
• Harsh environment signal selection

Procurement Notes

Verify that the specific suffix 'RH' corresponds to the Radiation Hardened variant as defined by the manufacturer's official documentation. Confirm QML-V qualification status through the Defense Logistics Agency (DLA) Standard Microcircuit Drawing (SMD) database. Ensure the hermetic seal integrity meets military specifications for the intended operational environment.

Selection Notes

Select this component when radiation tolerance and long-term reliability in vacuum or high-radiation environments are critical. The 54AC series offers higher speed than standard AC devices while maintaining low power consumption. Verify that the 2 V to 6 V operating range aligns with the system power supply architecture.

Part Context

This part belongs to the National Semiconductor 54AC/54ACT series of radiation-hardened CMOS logic functions. These components are engineered to meet stringent aerospace requirements, including resistance to total ionizing dose effects and single event phenomena. The series includes various logic gates, flip-flops, and multiplexers housed in durable hermetic packages.

Replacement Considerations

Check DLA SMD databases for equivalent qualified parts such as other 54AC151 variants from authorized manufacturers. Ensure any substitute maintains the same radiation hardness level and hermetic package type.
