SNJ54AHC273FK

Flip Flops Overview

The SNJ54AHC273FK is an automotive-grade octal D-type flip-flop manufactured by Texas Instruments. It features positive-edge triggering and a master reset function within the AHC logic family. The device utilizes a 20-lead LCCC ceramic package designed for high reliability in harsh environments. It operates across an extended temperature range of -55°C to 125°C, supporting supply voltages from 2V to 5.5V with push-pull outputs.

Flip Flops Feature Summary

• Automotive-grade qualification for reliable operation in demanding vehicle environments
• Octal configuration providing eight independent D-type storage elements
• Positive-edge clock triggering with dedicated master reset functionality
• Robust ceramic LCCC packaging suitable for high-temperature applications

Flip Flops Applications

• Automotive data acquisition systems requiring high-reliability memory storage
• Vehicle control unit interface circuits for signal latching
• Industrial logic control modules operating in extreme temperatures
• High-speed digital data buffering in aerospace electronics

Flip Flops Procurement Notes

Verify that the specific part number includes the 'FK' suffix to confirm the ceramic LCCC package and military/automotive grade specifications. Ensure compatibility with existing board layouts for the 20-lead quad flat no-lead form factor. Confirm that the procurement source provides traceability documentation required for automotive or defense applications. Check for lead-free compliance status if environmental regulations apply to the final assembly process.

Flip Flops Selection Notes

Select this component when designing systems that require octal D-flip-flops with automotive-grade reliability and wide temperature tolerance. The AHC series offers high speed and low power consumption compared to older logic families. Consider the ceramic package for superior thermal stability and hermetic sealing requirements. Evaluate the 2V to 5.5V supply range against system power constraints to ensure proper logic level interfacing.

Flip Flops Part Context

This device belongs to the SN54/74AHC273-Q1 family of octal D-type flip-flops. It shares functional similarities with other automotive-qualified logic devices but is distinguished by its specific ceramic packaging and extended temperature rating. The part is designed to meet stringent automotive standards while maintaining compatibility with standard digital logic interfaces.

Flip Flops Replacement Considerations

SNJ54AHC273FKR is a reel-based variant of the same functional device. SN74AHC273QWRKSRQ1 offers similar automotive-grade performance but uses a VQFN package instead of LCCC.
