SNJ54HC273FK

Flip Flops Overview

The SNJ54HC273FK is an octal D-type flip-flop with a clear input manufactured by Texas Instruments. It features eight independent D-type flip-flops, each equipped with a positive-edge clock and an asynchronous clear function. The device operates within a supply voltage range of 2.0V to 6.0V and supports data rates up to 16MHz. It is housed in a 20-pin LCCC package and is rated for an extended operating temperature range from -55°C to 125°C.

Flip Flops Feature Summary

• Octal configuration providing eight independent D-type flip-flops
• Positive-edge triggering mechanism for clock synchronization
• Asynchronous clear function to reset outputs independently of the clock
• Extended industrial temperature rating for harsh environments

Flip Flops Applications

• High-speed digital data storage systems
• Shift register implementations
• Parallel-to-serial conversion circuits
• Industrial control logic interfaces

Flip Flops Procurement Notes

Verify the specific suffix 'FK' corresponds to the 20-pin LCCC package variant when sourcing. Confirm that the component meets military-grade reliability standards if required for the application. Ensure compatibility with existing PCB footprints designed for the LCC20 form factor. Check for RoHS compliance status relative to current manufacturing batches.

Flip Flops Selection Notes

Select this component when an octal storage element with a global clear function is required. Consider the 16MHz maximum frequency limit for timing constraints. Evaluate the LCCC package suitability for high-reliability applications compared to other pin configurations. Ensure the supply voltage aligns with the 2.0V to 6.0V operational range.

Flip Flops Part Context

This part belongs to the SN54HC273 series of octal D-type flip-flops. It shares functional characteristics with other members of the HC family but differs in packaging and temperature rating. The SNJ prefix indicates a specific military or high-reliability grade variant produced by Texas Instruments.

Flip Flops Replacement Considerations

SNJ54HC273J is a documented alternative offering identical functionality in a 16-pin CDIP package. Verify pinout compatibility and thermal requirements before substitution.
