Overview
The 54AC86/SDA-R is a rad-hard quad exclusive OR gate manufactured by Rochester Electronics. It belongs to the 54ACxxxx series, composed of high-speed CMOS functions designed for aerospace radiation requirements. The device features high radiation hardness in total ionizing dose (TID), single event latch-up (SEL) immunity, and single event upset (SEU) characterization. It is housed in hermetic ceramic packages and is QML-V qualified, making it suitable for demanding space conditions.
Feature Summary
- High radiation hardness with TID ratings up to 300 krad(Si) RHA
- Immunity to single event latch-up (SEL) up to 110 MeV.cm²/mg
- Characterized for single event upset (SEU) and single event transient (SET)
- Housed in hermetic ceramic packages suitable for harsh environments
Applications
- Aerospace industry circuits requiring radiation tolerance
- Spacecraft systems operating in harsh environmental conditions
- Military applications necessitating QML-V qualification
Procurement Notes
Verify the specific package variant and suffix against official documentation, as the SDA-R designation implies a particular hermetic configuration. Confirm QML-V compliance status and radiation test reports directly with the manufacturer or authorized distributor to ensure suitability for critical mission applications.
Selection Notes
Select this component when radiation hardness is a primary design constraint. Ensure the system environment exceeds standard commercial limits for TID and SEL. Verify that the hermetic packaging meets the specific vacuum or pressure requirements of the target application compared to non-hermetic alternatives.
Part Context
This part is part of the 54ACxxxx series of high-speed CMOS logic functions. The series includes various gates, flip-flops, and multiplexers tailored for aerospace use. Rochester Electronics provides these components to meet the rigorous reliability standards required for satellite and deep-space missions.
Replacement Considerations
Direct replacements must be QML-V qualified rad-hard devices from the same family. Verify pinout compatibility and radiation specifications. Non-rad-hard equivalents are unsuitable for this application due to lack of radiation tolerance.
