Overview
The SN54AC14/BDA is a hex Schmitt inverter belonging to the 54AC series, manufactured by Rochester Electronics. It is designed for high-speed CMOS applications requiring radiation hardness and immunity to single-event latch-up (SEL) and upset (SEU). The component features hermetic packaging suitable for difficult environmental conditions. It operates within a supply voltage range of 2 V to 6 V and supports an operating temperature range from -55 °C to +125 °C. The device is qualified under SMD specifications.
Feature Summary
- Radiation hardened design with Total Ionizing Dose (TID) tolerance up to 300 krad (Si)
- Immunity to Single Event Latch-up (SEL) up to 110 MeV.cm²/mg
- Hermetic ceramic package construction for harsh environment reliability
- High-speed CMOS logic function compatible with aerospace industry requirements
Applications
- Aerospace electronic systems
- Spacecraft instrumentation
- Military communication equipment
- High-reliability digital logic circuits
Procurement Notes
Verify that the specific part number includes the /BDA suffix which denotes the hermetic package variant. Confirm compliance with SMD specifications if required for your assembly process. Ensure the supplier provides documentation verifying the radiation hardness qualifications and hermetic seal integrity as these are critical for the intended high-reliability applications.
Selection Notes
Select this component when radiation tolerance and hermetic sealing are mandatory. It serves as a high-speed inverter solution where standard commercial parts would fail due to environmental stress or ionizing radiation. Consider the 2 V to 6 V operating voltage range for power budgeting. Verify that the hex inverter configuration meets the circuit topology requirements.
Part Context
This part belongs to the 54AC series of high-speed CMOS functions developed for the aerospace industry. Rochester Electronics sources and qualifies these components to meet strict military and space standards. The series includes various gates, flip-flops, and bus interfaces, all sharing common radiation hardening characteristics and hermetic packaging options.
Replacement Considerations
Direct replacements must match the 54AC series specification and hermetic package type. Verify that any substitute maintains the same radiation hardness levels and SEL immunity ratings. Check pin compatibility and logical function equivalence before integration.
