Flip Flops datasheet and documents for SNJ54LVC74AFK

SNJ54LVC74AFK

Flip Flops Overview

The SNJ54LVC74AFK is a dual positive-edge-triggered D-type flip-flop manufactured by Texas Instruments. It features independent preset and clear inputs that set or reset outputs regardless of other input levels. The device operates within a supply voltage range of 2V to 6V, supporting standard TTL logic levels. It utilizes a 20-pin ceramic LCC package designed for high reliability applications. Key electrical characteristics include a maximum propagation delay of 10.5ns at 5V with 50pF load, complementary outputs, and a wide operating temperature range from -55°C to 125°C.

Flip Flops Feature Summary

Flip Flops Procurement Notes

Verify the specific suffix 'FK' against the official Texas Instruments datasheet to confirm the exact pinout, lead finish, and moisture sensitivity classification. Ensure compatibility with existing board layouts due to the specific 20-pin ceramic LCC package dimensions. Confirm that the supplier provides traceable documentation for military-grade components. Check for any recent production lifecycle notices or obsolescence warnings directly from the manufacturer before finalizing procurement plans.

Flip Flops Selection Notes

Select this component when dual D-type flip-flops are required in a ruggedized ceramic package. It is appropriate for designs needing complementary outputs and asynchronous control signals. Consider the 2V to 6V supply range for flexibility in power domains. Evaluate the 10.5ns propagation delay against system timing requirements. Ensure the design supports the thermal management needs associated with the specified operating temperature range.
