JM54AC541SRA-RH

Overview

The JM54AC541SRA-RH is a high-speed CMOS octal buffer and driver featuring three-state outputs, manufactured by National Semiconductor. It operates within a voltage range of 2 V to 6 V and supports an extended temperature range from -55 °C to +125 °C. The component is designed for aerospace applications, offering high radiation hardness with a total ionizing dose tolerance of 300 krad(Si) and immunity to single event latch-up up to 110 MeV.cm²/mg. It is housed in a hermetic ceramic package and is qualified under the QML-V standard.

Feature Summary

• High radiation hardness suitable for demanding space conditions
• Immunity to single event latch-up (SEL)
• Hermetic ceramic packaging for harsh environments

Applications

• Aerospace systems requiring radiation-hardened logic
• Harsh environmental electronic circuits
• Spacecraft bus interface designs

Procurement Notes

Verify that the specific part number includes the 'RH' suffix indicating radiation hardening and 'SRA' denoting the ceramic package style. Confirm QML-V qualification status through official manufacturer documentation or authorized distributors. Ensure compliance with SMD specifications if required for your program. Check for lead-free status and RoHS exemptions as military-grade parts may have different regulatory classifications.

Selection Notes

Select this component when radiation tolerance and hermetic sealing are critical requirements. Compare against other 54AC series devices for pin compatibility and electrical characteristics. Consider the operating voltage range of 2 V to 6 V for system power supply alignment. Evaluate thermal performance within the specified -55 °C to +125 °C range for your application environment.

Part Context

This device belongs to the 54ACxxxx series of high-speed CMOS functions designed for aerospace industry radiation requirements. It provides octal buffering capabilities with three-state outputs. The series includes various gates, flip-flops, and bus interfaces, all characterized for high total ionizing dose tolerance and single event upset resilience in hermetic packages.

Replacement Considerations

Check for equivalent radiation-hardened octal buffers from Texas Instruments or STMicroelectronics. Verify pinout compatibility and electrical specifications before substitution. Ensure any replacement maintains QML-V qualification if mandated by your design.
