SNJ54LVT573FK

Overview

The SNJ54LVT573FK is a military-grade octal D-type transparent latch manufactured by Texas Instruments. It operates within a supply voltage range of 2.7 V to 3.6 V and features three-state outputs with low on-resistance. The device provides high noise immunity and is designed for robust performance in demanding environments. Key electrical characteristics include a propagation delay of 2.9 ns at 3.3 V, a static current of 5 mA, and output drive capabilities of 32 mA for both high and low states. It supports an operating temperature range from -55°C to +125°C.

Feature Summary

• Military-grade construction ensuring reliability in extreme conditions
• Octal configuration providing eight independent D-type latches
• Three-state outputs allowing direct bus interfacing
• Low on-resistance outputs for efficient signal transmission

Applications

• Military aerospace systems requiring high reliability
• Harsh environment data acquisition modules
• Industrial control systems with strict temperature tolerances
• Defense communication equipment interfaces

Procurement Notes

Verify the specific suffix 'FK' indicates military grade qualification and RoHS non-compliance status as per manufacturer documentation. Confirm package type and terminal form details against the official datasheet before integration. Ensure supply chain sources provide valid traceability for military specifications. Check for any obsolescence notices or lifecycle changes directly from Texas Instruments.

Selection Notes

Select this component when military-grade environmental tolerance is required alongside standard LVTH logic functionality. Compare against commercial variants like SN74LVTH573 if cost is a primary constraint and harsh environment operation is not necessary. Verify that the 3.3 V supply voltage aligns with system power rails. Consider the package availability and lead times associated with military-specification parts versus commercial equivalents.

Part Context

This part belongs to the SN54/74LVT series of logic integrated circuits. It serves as an octal latch variant within the broader family of Texas Instruments logic products. The LVT series is characterized by low voltage operation and compatibility with various logic families. This specific military version shares functional similarities with commercial counterparts but differs in qualification standards and environmental ratings.

Replacement Considerations

Commercial equivalents such as SN74LVTH573 may be considered if military qualification is not required. Verify pinout compatibility and electrical parameter alignment before substitution. Note that commercial versions lack the extended temperature range and radiation hardness typically associated with military-grade parts.
