• Harsh environment data storage applications

Latches Procurement Notes

Verify that the specific order includes the /883 suffix to ensure the component meets the required military-grade specifications. Confirm the presence of ESCC qualification documentation and check for the appropriate screening level (e.g., 38534H or 38535Q) as defined in the manufacturer's technical notes. Ensure the procurement matches the exact ceramic package requirements for your application.

Latches Selection Notes

Select this component when standard commercial logic devices are insufficient due to radiation exposure or extreme temperature conditions. The M54HC series is designed to meet specific aerospace industry requirements, offering higher reliability than standard plastic-packaged equivalents. Consider the wider operating voltage range and thermal stability when designing for variable power environments.

Latches Part Context

This part belongs to the M54HCxxx and M54HCTxxx series of CMOS functions. These series are composed of gates, flip-flops, multiplexers, counters, and bus interfaces specifically designed for the aerospace industry. They feature high single-event latch-up immunity and are housed in ceramic hermetic packages, making them ideal for space missions and other demanding operational scenarios.
