JM54AC74SDA-RH

Overview

The JM54AC74SDA-RH is a dual D-type flip-flop with preset and clear, part of the 54AC series designed for aerospace applications. It features radiation hardness up to 300 krad (Si) total ionizing dose and immunity to single event latch-up up to 110 MeV.cm²/mg. The device operates within a voltage range of 2 V to 6 V and supports temperatures from -55 °C to +125 °C. It is housed in hermetic packages and complies with SMD specifications.

Feature Summary

• Radiation hardened design suitable for harsh environments
• Immunity to single event latch-up and upset
• Hermetic packaging for environmental protection

Applications

• Aerospace systems
• Military electronics
• High-reliability computing

Procurement Notes

Verify that the specific order includes the RHA QML-V qualification suffix as documented. Confirm the package type matches the required hermetic specification. Ensure the component meets the SMD standard microcircuit drawing requirements specified by the Defense Logistics Agency for the intended application environment.

Selection Notes

Select this component when high radiation tolerance and single-event effects immunity are critical. The wide operating voltage range allows flexibility in power supply design. Hermetic packaging ensures reliability in extreme temperature conditions typical of space or military missions.

Part Context

This part belongs to the 54ACxxxx series of high-speed CMOS functions. The series is specifically engineered to meet stringent radiation requirements for the aerospace industry. It includes various logic functions such as gates, flip-flops, and counters, all built on a process qualified under Mil-Prf-38535 standards.

Replacement Considerations

Direct replacements must also be QML-V qualified and hermetically sealed. Verify compatibility with existing radiation hardening protocols. Ensure the substitute maintains the same SEL immunity levels and operating voltage ranges.
