SNJ54195W

Shift Registers Overview

The SNJ54195W is a military-grade, 4-bit parallel-access shift register manufactured by Texas Instruments. It features parallel input and output capabilities with serial input functionality. The device operates within the standard military temperature range and utilizes a Ceramic Flatpack (CFP) package designated as W. This component is part of the SN54 series, designed for high-reliability applications requiring robust performance under extreme environmental conditions.

Shift Registers Feature Summary

• Supports 4-bit data storage with simultaneous parallel access
• Military-grade construction for extended temperature operation
• Capable of shifting data serially or loading in parallel

Shift Registers Applications

• Military aerospace logic systems
• High-reliability industrial control circuits
• Data storage in harsh environment computing

Shift Registers Procurement Notes

Verify the obsolete status and CFP package availability through authorized channels. Confirm that the military grade designation aligns with specific project reliability requirements. Ensure compatibility with existing ceramic flatpack footprints during integration planning.

Shift Registers Selection Notes

Select this component when military temperature ratings and high reliability are mandatory. The parallel-access feature suits designs needing rapid data retrieval. Consider the CFP package constraints for board layout and thermal management in enclosed military enclosures.

Shift Registers Part Context

This part belongs to the SN54 family of logic integrated circuits, distinguished from the commercial SN74 series by its wider operating temperature range and stricter manufacturing controls. The SNJ54195W specifically provides 4-bit shift register functionality with parallel I/O, serving legacy military and aerospace electronic architectures.
