JM54ACT151BEA-R

Overview

The JM54ACT151BEA-R is a high-speed CMOS 8-channel multiplexer from the 54ACT series, designed for aerospace and radiation-hardened applications. It operates within a 4.5 V to 5.5 V supply range and features hermetic ceramic packaging. The component provides radiation hardness of 300 krad (Si) total ionizing dose tolerance and immunity to single event latch-up up to 110 MeV.cm²/mg. It supports an operating temperature range of -55 °C to +125 °C and complies with SMD specifications.

Feature Summary

• Radiation hardened design suitable for harsh space environments
• Immunity to single event latch-up and upset effects
• Hermetic ceramic package construction for environmental sealing

Applications

• Aerospace signal routing systems
• Harsh environment data acquisition
• Military communication interfaces

Procurement Notes

Verify that the specific part number matches the required QML-V qualification level and SMD standard compliance. Confirm the presence of the hermetic seal and radiation test reports. Ensure the ordering suffix corresponds to the correct package variant and lead finish as defined in the manufacturer's documentation.

Selection Notes

Select this component when radiation tolerance and single event immunity are critical requirements. The 54ACT series offers TTL-compatible logic levels while maintaining CMOS power characteristics. Verify that the 8-channel multiplexing function aligns with the system architecture needs.

Part Context

This device belongs to the 54AC/54ACT family of high-speed CMOS functions. The series includes various gates, flip-flops, and bus interfaces tailored for demanding conditions. STMicroelectronics guarantees compliance with qualified parts specifications for these radiation-hardened components.

Replacement Considerations

Check for other 54ACT151 variants with compatible radiation qualifications. Verify pinout compatibility with existing board layouts. Ensure substitute parts meet the same TID and SEL immunity thresholds.
