Overview
The 54AC14/QCA is a radiation-hardened hex Schmitt inverter manufactured by Rochester Electronics. It belongs to the high-speed CMOS 54AC series, designed for aerospace and harsh environments. The device features hermetic packaging and immunity to single-event latch-up (SEL) and upset (SEU). It operates within a voltage range of 2 V to 6 V and supports temperatures from -55 °C to +125 °C. Radiation tolerance reaches 300 krad (Si) total ionizing dose.
Feature Summary
- Radiation hardness with immunity to single event latch-up and upset
- Hermetic ceramic package construction for environmental protection
- High-speed CMOS technology optimized for low power consumption
Applications
- Aerospace satellite systems
- Spacecraft digital logic circuits
- Harsh environment military electronics
Procurement Notes
Verify component authenticity through authorized distributors or certified sources. Confirm radiation qualification status and hermetic seal integrity upon receipt. Ensure storage conditions maintain package integrity prior to installation. Review specific datasheet revisions for any updates to electrical characteristics or handling instructions.
Selection Notes
Select this component for applications requiring high radiation tolerance and hermetic sealing. Suitable for designs operating between 2 V and 6 V. Consider thermal management for high-temperature environments up to 125 °C. Verify pin compatibility if replacing legacy parts.
Part Context
Rochester Electronics specializes in sourcing and distributing obsolete and hard-to-find components. This part is part of their rad-hard portfolio, ensuring availability for long-life aerospace programs. The QCA suffix typically denotes a specific package or qualification variant within the standard 54AC14 family.
Replacement Considerations
Direct replacements include other rad-hard 54AC14 variants from qualified manufacturers. Verify pinout and electrical specifications match exactly. Non-rad-hard equivalents lack necessary radiation tolerance and should not be used in space applications.
