JM54AC174S2A-RH

Flip Flops Overview

The JM54AC174S2A-RH is a hex D-type flip-flop with clear, belonging to the 54AC/ACT series of high-speed CMOS logic functions. Designed for aerospace applications, it features radiation hardness up to 300 krad (Si) total ionizing dose and immunity from single event latch-up. The device operates within a voltage range of 2 V to 6 V for the AC series and utilizes hermetic ceramic packages suitable for harsh environments.

Flip Flops Feature Summary

• High radiation hardness designed for aerospace requirements
• Immunity to single event latch-up and upset
• Hermetic ceramic packaging for environmental protection

Flip Flops Applications

• Aerospace systems requiring radiation tolerance
• Harsh environment electronic circuits
• Spacecraft data processing units

Flip Flops Procurement Notes

Verify that the specific suffix indicates the correct radiation-hardened variant and hermetic package type. Confirm compliance with SMD specifications if required by the procurement specification. Ensure the supplier provides documentation verifying the QML-V qualification status and test reports corresponding to the military standard microcircuit drawing.

Flip Flops Selection Notes

Select this component when radiation tolerance and single-event immunity are critical design constraints. It is suitable for applications operating between -55 °C and +125 °C. Consider the 54AC series for lower voltage operation or 54ACT for TTL compatibility depending on the system interface requirements.

Flip Flops Part Context

This part is part of the 54ACxxxx and 54ACTxxxx series produced by STMicroelectronics under license or acquisition. These series are specifically engineered to meet stringent radiation requirements for the aerospace industry, offering a comprehensive set of logic functions including gates, flip-flops, and counters in hermetic packages.

Flip Flops Replacement Considerations

Direct replacements include other QML-V qualified hex D-type flip-flops from the same series such as the 54AC174 or 54ACT174 variants. Verify that any substitute maintains the same radiation hardness levels and hermetic package configuration to ensure environmental compatibility.
