Overview
The Rochester Electronics LLC 54H22/BCA is a rad-hard Quad 2-Input NAND gate from the 54HC/HCT series, designed for aerospace and high-reliability applications. It features ceramic hermetic packaging and ESCC qualification. The device operates on a supply voltage of 2 V to 6 V with an operating temperature range of -55 °C to +125 °C. It offers total dose hardness up to 50 krad(Si) and immunity to single event latch-up (SEL).
Feature Summary
- Radiation hardened design suitable for space environments
- Ceramic hermetic package construction
- ESCC qualified for high-reliability standards
Applications
- Spacecraft logic circuits
- Harsh environmental systems
- High-reliability digital processing
Procurement Notes
Verify the specific ESCC part number against the European Space Components Coordination database to confirm compliance with detailed specifications. Ensure the ceramic hermetic package integrity matches mission requirements. Confirm radiation hardness levels align with the intended operational environment.
Selection Notes
Select this component when radiation tolerance and hermetic sealing are critical. It serves as a drop-in replacement for standard 54HC22 devices in harsh environments. Verify voltage compatibility within the 2 V to 6 V range. Check SEL immunity requirements against mission profiles.
Part Context
This part belongs to the rad-hard 54HC/HCT series by STMicroelectronics, now distributed by Rochester Electronics. The series includes various CMOS functions like gates, flip-flops, and counters. These components are engineered to meet strict aerospace industry radiation requirements while maintaining high-speed performance.
Replacement Considerations
Standard commercial 54HC22 parts lack radiation hardness and hermetic sealing. Verify if non-hermetic alternatives meet environmental constraints. Cross-reference ESCC specifications for equivalent rad-hard quad NAND gates.
