JM54AC273BSA-RH

Overview

The JM54AC273BSA-RH is a rad-hard octal D-type flip-flop with clear, designed for aerospace and harsh environments. It operates on a 2 V to 6 V supply voltage. The device features high radiation hardness, including 300 krad(Si) total ionizing dose tolerance and immunity to single event latch-up up to 110 MeV.cm²/mg. It is housed in a hermetic ceramic SOIC-20 package and supports a temperature range of -55 °C to +125 °C.

Feature Summary

• High radiation hardness suitable for demanding space conditions
• Immunity from single event latch-up (SEL)
• Hermetic ceramic packaging for environmental protection

Applications

• Aerospace systems requiring radiation tolerance
• Harsh environmental electronic applications
• Spacecraft data storage and bus interfaces

Procurement Notes

Verify the specific manufacturer source, as National Semiconductor was acquired by Texas Instruments. Confirm that the part number corresponds to the correct QML-V qualified or engineering model version required for your project. Ensure the hermetic seal integrity matches your environmental specifications before procurement.

Selection Notes

Select this component when radiation hardness is critical. Compare against standard commercial variants if operating in non-radiation environments to optimize cost. Verify the package type and lead configuration match your PCB layout requirements for hermetic DIP or SOIC options.

Part Context

This part belongs to the 54AC series of high-speed CMOS functions. It is specifically engineered to meet the stringent radiation requirements of the aerospace industry. The series includes various logic gates, flip-flops, and counters, all characterized for single event upset and latch-up immunity.
