ACTS74HMSR-02

Overview

The ACTS74HMSR-02 is a radiation-hardened dual D-type flip-flop die manufactured by Renesas Electronics Corporation. It features two independent positive-edge-triggered elements, each with Set and Reset capabilities. Designed for high-reliability environments, this component utilizes advanced semiconductor processes to withstand ionizing radiation effects. The device provides robust data storage functionality suitable for aerospace and defense applications where standard commercial components may fail due to single-event upsets or latch-up conditions.

Feature Summary

• Radiation-hardened design for space and high-radiation environments
• Dual independent D-type flip-flop elements per package
• Positive-edge triggering mechanism for precise timing control
• Integrated Set and Reset inputs for direct state management

Applications

• Aerospace satellite communication systems
• Defense electronics requiring radiation tolerance
• High-reliability industrial control logic
• Spacecraft data processing units

Procurement Notes

Verify radiation hardness qualification levels and specific lot traceability requirements before procurement. Confirm that the die form factor matches your custom packaging or substrate integration capabilities. Ensure compatibility with existing drive circuits and voltage levels. Check for any specific handling instructions related to sensitive semiconductor dies. Validate that the component meets all necessary environmental testing standards for your target application.

Selection Notes

Select this component when radiation tolerance is critical and standard CMOS logic fails. Consider the dual-element architecture for space-constrained designs. Evaluate the need for Set/Reset functionality versus simple clocked storage. Assess thermal management requirements for bare die implementations. Compare against other radiation-hardened families for pinout and speed compatibility.

Part Context

This part belongs to Renesas' specialized radiation-hardened product line, distinct from their commercial logic offerings. It complements other hardened memory and logic devices used in mission-critical systems. The SuperH and SH7040 series mentioned in general knowledge are unrelated microcontrollers; this component is purely digital logic.

Replacement Considerations
