SNJ54F540J

Overview

The SNJ54F540J is an octal buffer and line driver featuring three-state outputs, manufactured by Texas Instruments. It operates within a military-grade temperature range of -55°C to 125°C and utilizes a 20-pin ceramic dual in-line package (CDIP). The device belongs to the F/FAST logic series and functions as a unidirectional bus driver with inverted output polarity. It incorporates dual output enable controls to manage data flow directionality effectively.

Feature Summary

Octal buffering capability for high-density signal transmission
Three-state outputs allowing multiple drivers on shared buses
Inverted output polarity for flexible logic interfacing
Dual independent output enables for precise control

Applications

Military aerospace communication systems
High-reliability industrial bus architectures
Harsh environment data acquisition interfaces

Procurement Notes

Verify the specific suffix 'J' confirms the ceramic DIP package and military temperature rating. Confirm RoHS compliance status as indicated in related datasheets. Ensure the ordering part number matches the exact functional requirements for inverted octal buffering.

Selection Notes

Select this component when designing for extreme temperature environments requiring robust signal isolation. The inverted output configuration simplifies interface design for specific logic families. Verify pin compatibility if replacing older legacy components in existing military hardware designs.

Part Context

This device is part of the broader SNJ54Fxx family of high-speed logic circuits designed for demanding applications. It shares architectural similarities with other octal buffers but distinguishes itself through its specific inversion characteristics and ruggedized packaging suitable for defense and space sectors.

Replacement Considerations

Consider the SNJ54F241J for non-inverted octal buffering applications. For AHCT/VHCT technology replacements, evaluate the SNJ54AHCT540J, noting voltage level differences between F and AHCT series.
