SNJ54LS73AW

Flip Flops Overview

The SNJ54LS73AW is a dual negative edge triggered J-K flip-flop from the Texas Instruments LS series. It features complementary outputs and master-slave operation within a 14-lead ceramic flatpack (CDFP) package. The device operates across an extended temperature range of -55°C to 125°C, suitable for military applications. Key electrical parameters include a maximum propagation delay of 150 ns, a maximum supply current of 1.44 mA, and a load capacitance specification of 50 pF.

Flip Flops Feature Summary

• Dual negative edge triggered J-K flip-flop configuration with complementary outputs
• Master-slave operation architecture for reliable data storage
• Extended temperature rating supporting -55°C to 125°C operation
• Hermetically sealed ceramic flatpack construction

Flip Flops Applications

• Military-grade digital logic circuits
• High-reliability computing systems

Flip Flops Procurement Notes

Verify the specific suffix 'AW' against official Texas Instruments documentation to confirm exact pinout, lead finish, and manufacturing lot details. Ensure the procurement source provides traceability certificates required for military or aerospace components. Cross-reference the CDFP-14 package dimensions with mechanical drawings prior to integration into PCB layouts.

Flip Flops Selection Notes

Select this component when dual J-K flip-flops with complementary outputs are required in harsh environments. The LS series offers standard TTL compatibility while maintaining low power consumption. The ceramic package provides superior environmental protection compared to plastic variants. Consider the 150 ns propagation delay for timing constraints in high-speed military applications.

Flip Flops Part Context

This part belongs to the SN54/74LSxx series of logic integrated circuits. The 'SNJ' prefix indicates a military-rated device manufactured by Texas Instruments. The LS designation signifies Low-power Schottky technology, which balances speed and power efficiency. The AW suffix typically denotes specific packaging or testing variations within the military grade lineup.

Flip Flops Replacement Considerations

Direct replacements must match the SN54LS73AW specifications, including the dual J-K flip-flop function, complementary outputs, and CDFP-14 ceramic package. Verify that substitute parts meet the same -55°C to 125°C temperature range and military qualification standards.
