SNJ54HC273J

Flip Flops Overview

The SNJ54HC273J is an octal D-type edge-triggered flip-flop manufactured by Texas Instruments. It features a single clock input and eight data inputs, with outputs that are not inverted relative to the inputs. The device includes a master reset function to initialize the state of all flip-flops simultaneously. It is housed in a 20-lead ceramic dual in-line package (CDIP) designed for high reliability. The component operates within a supply voltage range of 2V to 6V and supports a wide operating temperature range from -55°C to 125°C, suitable for military and aerospace applications.

Flip Flops Feature Summary

• Octal configuration providing eight independent D-type storage elements within a single integrated circuit
• Positive-edge triggering mechanism synchronized by a single clock input for precise timing control
• Master reset functionality allows simultaneous initialization of all output states regardless of clock or data conditions
• Non-inverting output structure ensures logical consistency between input data and stored output values

Flip Flops Applications

• Military-grade digital logic systems requiring extended temperature stability
• Aerospace computing architectures utilizing radiation-hardened or high-reliability components
• Industrial control systems demanding robust data storage under harsh environmental conditions
• High-speed serial-to-parallel conversion circuits in communication equipment

Flip Flops Procurement Notes

Verify the authenticity of the SNJ54HC273J through authorized distributors or direct manufacturer channels due to its specialized military grade status. Confirm the presence of the 'J' suffix indicating the ceramic dual in-line package variant. Ensure compliance with export control regulations such as EAR99 classifications if applicable to your region. Request detailed lot traceability and material composition reports to validate suitability for critical infrastructure or defense projects.

Flip Flops Selection Notes

Select the SNJ54HC273J when system requirements dictate the need for octal data latching with high noise immunity provided by HC logic family characteristics. Consider this component over standard plastic packages if mechanical durability and hermetic sealing are necessary for long-term operational integrity. Evaluate the 2V to 6V supply range compatibility with existing power rails before integration into the design architecture.

Flip Flops Part Context

This component belongs to the SN54HC series of high-speed CMOS logic devices produced by Texas Instruments. The SN54 designation indicates qualification for military specifications including extended temperature ranges and strict manufacturing controls. As part of the HC family, it offers performance comparable to the older LS series but with lower power consumption and wider voltage tolerance, making it suitable for modern low-power digital designs.

Flip Flops Replacement Considerations

Direct pin-compatible alternatives include the SN54HC273 without the J suffix for non-hermetic applications. For enhanced speed requirements, consider the SN54ACT273J which maintains similar functionality with faster switching characteristics. Verify that any substitute component matches the required CDIP package dimensions and thermal handling capabilities.
