RHFAC32K1

Overview

The RHFAC32K1 is a rad-hard quad 2-input OR gate manufactured by STMicroelectronics. It operates within a supply voltage range of 2V to 6V and supports an extended operating temperature range from -55°C to +125°C. The component is housed in a 14-CFlatPack surface-mount package, designed for high-reliability applications requiring radiation tolerance.

Feature Summary

• Rad-hardened design for radiation tolerance
• Quad 2-input OR logic function
• Extended industrial temperature range capability

Applications

• Spacecraft avionics systems
• Satellite communication payloads
• High-reliability military electronics

Procurement Notes

Verify the specific engineering model status with STMicroelectronics before procurement. Confirm that the 14-CFlatPack package dimensions match your PCB layout requirements. Ensure your system design accommodates the specified 2V to 6V supply voltage range. Validate radiation hardness levels against your mission profile requirements.

Selection Notes

Select this component when radiation hardness is critical for the application environment. The quad configuration provides multiple logic gates in a single package, reducing board space. Consider the CFlatPack package for surface-mount assembly compatibility. Verify thermal management needs given the wide operating temperature range.

Part Context

This part belongs to STMicroelectronics' rad-hardened logic gate family. It complements other radiation-tolerant components used in aerospace and defense electronics. The series focuses on reliability in harsh environments where standard commercial parts would fail due to ionizing radiation effects.

Replacement Considerations

Check for direct pin-compatible rad-hard alternatives from STMicroelectronics or other qualified vendors. Verify that any substitute maintains the same radiation hardness qualification level. Ensure logical equivalence and electrical characteristics match the original design specifications.
