Flip Flops datasheet and documents for SNJ54ALS174J

SNJ54ALS174J

Flip Flops Overview

The SNJ54ALS174J is a military-grade Hex D-type flip-flop manufactured by Texas Instruments. It operates within a temperature range of -55°C to 125°C and utilizes a 16-lead ceramic dual in-line package (CDIP). The device features true outputs with an active-low clear function, designed for high-reliability applications requiring robust performance under extreme environmental conditions.

Flip Flops Feature Summary

Hex configuration providing six independent D-type flip-flops within a single package
Active-low asynchronous clear input for immediate output reset
Military-grade construction ensuring reliability across extended temperature ranges
True output polarity compatible with standard logic interfaces

Flip Flops Applications

High-reliability aerospace data storage systems
Military communication equipment register banks
Avionics control logic state retention
Harsh environment industrial computing memory modules

Flip Flops Procurement Notes

Verify the specific suffix J indicates the ceramic dual in-line package variant when sourcing. Confirm that the component meets the required military specifications for the intended operational environment. Ensure compatibility with existing board layouts regarding the 16-lead CDIP footprint. Validate that the supply chain adheres to strict quality standards for defense and aerospace procurement requirements.

Flip Flops Selection Notes

Select this component when hex D-type flip-flops are required for military or aerospace applications. It is suitable for designs needing operation at temperatures up to 125°C. Choose this part over commercial variants if extended thermal stability and ruggedized packaging are mandatory. Consider the ALS series speed characteristics relative to system timing requirements.
