SNJ54F299FK

Shift Registers Overview

The SNJ54F299FK is an 8-bit universal shift/storage register from the Texas Instruments F/FAST logic series. It features parallel-in/parallel-out capabilities and bidirectional data shifting. The device utilizes bipolar technology with true outputs and operates within a military temperature range of -55°C to +125°C. It is housed in a 20-lead CQCC (Ceramic Quad Chip Carrier) package, designated as CQCC20. The component supports serial/parallel to serial/parallel counting sequences and includes asynchronous reset functionality.

Shift Registers Feature Summary

• Supports bidirectional data shifting and parallel storage operations
• Features true outputs compatible with TTL logic levels
• Designed for military-grade environmental reliability

Shift Registers Applications

• Military aerospace data processing systems
• High-reliability industrial control interfaces
• Bidirectional data buffering in harsh environments

Shift Registers Procurement Notes

Verify the specific suffix 'FK' corresponds to the ceramic quad chip carrier package and military temperature rating. Confirm that the component meets all required MIL-SPEC standards for your application environment. Ensure compatibility with existing board layouts for the 20-lead CQCC form factor before finalizing procurement orders.

Shift Registers Selection Notes

Select this component when military-grade temperature stability and high-speed bipolar logic performance are required. The F-series offers faster propagation delays compared to standard 74-series counterparts. Consider the CQCC package constraints for thermal management and PCB space availability in ruggedized designs.

Shift Registers Part Context

This part belongs to the SN54F299 family of 8-bit universal shift registers. The SN54 series denotes military qualification, distinguishing it from the commercial SN74 series. It serves as a robust solution for data manipulation tasks requiring wide operating temperature ranges and high noise immunity in critical infrastructure applications.

Shift Registers Replacement Considerations

Direct replacements include other SN54F299 variants with compatible pinouts. Verify package equivalence between CQCC20 and alternative ceramic packages. Cross-reference electrical specifications to ensure timing parameters meet system requirements.
