• Dual D-type flip-flops with positive-edge clock triggering
• Independent active-low preset and clear control inputs
• Military-grade temperature rating spanning -55°C to 125°C
• High-speed operation supporting data rates up to 35 MHz

Flip Flops Applications

• Military avionics data processing systems
• Aerospace telemetry and communication circuits
• Ruggedized industrial control logic registers
• Spacecraft onboard computer memory elements

Flip Flops Procurement Notes

Verify the specific suffix 'W' confirms the ceramic flatpack package variant. Confirm that the 'A' designation aligns with the LS family specifications. Ensure procurement channels provide traceability documentation required for defense or aerospace contracts. Validate that the component meets all environmental standards for the intended operational zone.

Flip Flops Selection Notes

Select this component when high radiation tolerance and wide temperature stability are mandatory. Choose over plastic variants if mechanical robustness against vibration is critical. Consider the ceramic package for hermetic sealing requirements. Evaluate pin compatibility if replacing older military-spec designs in existing hardware architectures.

Flip Flops Part Context

This part belongs to the SN54LS74A family, which provides dual edge-triggered D flip-flops. The SNJ prefix indicates a military-grade qualification level. The LS series offers low power dissipation compared to standard TTL. The ceramic flatpack construction distinguishes it from commercial plastic DIP versions.

Flip Flops Replacement Considerations

SNJ54LS74AJ: Ceramic DIP package variant. SNJ54LS74AW/883: Enhanced military screening option.
