Overview
The 54AC14/BCA is a hex Schmitt inverter belonging to the 54AC series, designed for aerospace and high-reliability applications. It features radiation hardness of 300 krad (Si) total ionizing dose tolerance and immunity from single event latch-up up to 110 MeV.cm²/mg. The device operates within a voltage range of 2 V to 6 V and supports a temperature range of -55 °C to +125 °C. It is available in hermetic packages compliant with SMD specifications.
Feature Summary
- Radiation hardened design suitable for difficult environmental conditions
- Immunity from single event latch-up and upset
- Hermetic packaging options available
Applications
- Aerospace industry circuits requiring radiation tolerance
- Military electronic systems operating in extreme temperatures
- Spacecraft instrumentation and control logic
Procurement Notes
Verify that the specific order includes the BCA suffix if hermetic packaging is required, as package type availability may vary. Confirm compliance with SMD specifications and QML-V qualification status directly with the manufacturer or authorized distributor before procurement. Ensure the component meets the required radiation hardness specifications for the intended mission profile.
Selection Notes
Select this component when radiation hardness and wide temperature operation are critical requirements. The 54AC14/BCA is appropriate for designs needing Schmitt trigger inputs to ensure clean signal transitions in noisy environments. Verify that the 2 V to 6 V operating voltage range aligns with the system power supply constraints.
Part Context
This part is part of the 54ACxxxx series of high-speed CMOS functions manufactured by STMicroelectronics and distributed by Rochester Electronics. The series is specifically engineered to meet the rigorous radiation requirements of the aerospace sector, offering robust performance in harsh environments where standard commercial components would fail.
