SNJ54LS595J

Overview

The SNJ54LS595J is an 8-bit shift register with output latches manufactured by Texas Instruments. It operates within a military-grade temperature range of -55°C to 125°C and utilizes a 16-pin Ceramic Dual In-Line Package (CDIP). The device functions as a serial-in parallel-out logic integrated circuit, featuring registered parallel outputs for data stability. It belongs to the LS logic series and supports right-counting directionality.

Feature Summary

• Provides serial-to-parallel data conversion capabilities with registered parallel outputs
• Designed for operation in extreme environmental conditions ranging from -55°C to 125°C
• Constructed using hermetically sealed ceramic packaging for durability

Applications

• Military electronic systems requiring high reliability
• Aerospace instrumentation and control circuits
• Industrial environments with extended temperature demands

Procurement Notes

Verify the specific ordering suffix J confirms the ceramic DIP package and military temperature rating. Ensure compatibility with existing board layouts designed for 16-pin CDIP footprints. Confirm that the LS logic family voltage requirements align with the target system design before procurement.

Selection Notes

Select this component when military-grade thermal performance and hermetic sealing are mandatory. The SNJ54LS595J is suitable for applications where standard plastic packages cannot withstand operational temperatures or harsh environmental exposure. Consider the LS series propagation characteristics relative to system timing constraints.

Part Context

This part is a member of the SNJ54LS59x family, which includes variants like the SNJ54LS593J00. These components share the LS logic architecture but differ in internal functionality, such as binary counting versus shift registration. The SNJ54LS595J specifically focuses on data storage and shifting operations rather than counting sequences.

Replacement Considerations

Direct substitutes include other SNJ54LS595 variants with compatible pinouts. Verify that any replacement maintains the same ceramic package dimensions and electrical specifications to ensure mechanical and functional interchangeability without redesign.
