JM54AC273SRA-RH

Overview

The JM54AC273SRA-RH is a radiation-hardened octal D-type flip-flop with clear, part of the 54AC series designed for aerospace environments. It features hermetic packaging to ensure immunity from single-event latch-up and upset. The device operates on a 2V to 6V supply voltage and withstands total ionizing doses up to 300 krad (Si). It supports a wide temperature range from -55°C to +125°C and complies with SMD specifications.

Feature Summary

• Radiation hardness qualification including TID and SEL immunity
• Hermetic package construction for difficult environmental conditions
• Octal D-type flip-flop functionality with clear input

Applications

• Aerospace industry circuits requiring radiation tolerance
• Satellite communication systems
• Spacecraft data handling units

Procurement Notes

Verify that the specific suffix 'SRA-RH' corresponds to the required hermetic package and radiation qualification level. Confirm compliance with SMD specifications and QML-V requirements if mandated by the project. Ensure the manufacturer documentation explicitly lists this part number as qualified for the stated radiation parameters before procurement.

Selection Notes

Select this component when high-speed CMOS logic is required in high-radiation environments. The 54AC series offers speed advantages over standard HC/UH types. Hermetic packaging is essential for long-duration space missions or military applications where single-event effects must be mitigated through hardware design rather than error correction.

Part Context

This part belongs to the 54ACxxxx family of high-speed CMOS functions manufactured by STMicroelectronics under license or acquisition from National Semiconductor heritage. The 54AC series is specifically engineered to meet stringent aerospace standards, providing robust performance in harsh electromagnetic and radiative conditions compared to commercial-grade equivalents.
