• Synchronous 4-bit binary counting with asynchronous clear functionality

Counter Dividers Applications

• Aerospace systems requiring radiation tolerance
• Harsh environmental electronic circuits
• Military-grade digital logic applications

Counter Dividers Procurement Notes

Verify the specific suffix 'R-H' indicates the correct radiation-hardened variant and hermetic sealing status against official manufacturer documentation. Confirm that the part number aligns with current DLA or manufacturer availability lists for QML-V qualified components. Ensure all ordering details match the exact hermetic package requirements specified in the technical data sheet.

Counter Dividers Selection Notes

Select this component when radiation hardness is critical for system longevity in space or high-radiation environments. It is appropriate for designs requiring hermetic sealing and operation across wide temperature extremes. Consider its synchronous architecture and asynchronous clear feature for precise timing control in complex digital logic sequences where standard commercial parts would fail due to radiation effects.

Counter Dividers Part Context

This part belongs to the 54AC series of high-speed CMOS functions, specifically engineered to meet stringent radiation requirements for the aerospace industry. It complements other radiation-hardened logic gates, flip-flops, and counters within the same family, providing standardized interfaces and performance characteristics for robust digital system design in hostile environments.

Counter Dividers Replacement Considerations

Direct substitutes must be verified through official DLA or manufacturer cross-reference lists for QML-V qualified equivalents. Generic commercial AC161 variants lack the necessary radiation hardness and hermetic sealing, making them unsuitable replacements for this specific application without rigorous qualification testing.
