Procurement Notes

Verify that the specific part number matches the required radiation hardness level and hermetic sealing standards. Confirm compliance with Standard Microcircuit Drawing (SMD) specifications as guaranteed by the manufacturer. Ensure the procurement channel provides traceability documentation for qualified parts meeting the defined environmental and electrical criteria.

Selection Notes

Select this component when designing systems for space or high-altitude operations where radiation effects are critical. The 54AC series offers high-speed performance suitable for complex logic functions. Consider the hermetic package requirement if moisture or contamination resistance is necessary alongside radiation hardness.

Part Context

This part is part of the broader 54AC/54ACT family of radiation-hardened logic devices. These components are engineered to meet stringent aerospace industry requirements. The family includes various gates, flip-flops, and multiplexers, all sharing common radiation tolerance characteristics and hermetic packaging options.

Replacement Considerations

Equivalent radiation-hardened octal D-type flip-flops with three-state outputs from other manufacturers may be considered. Verify that any substitute meets the same 300 krad (Si) TID rating and SEL immunity levels. Ensure the replacement maintains compatibility with the 2 V to 6 V operating voltage range.
