Procurement Notes

Verify that the component is sourced from authorized distributors to ensure authenticity. Confirm the presence of the 'DM' prefix indicating military grade. Check for compliance with specific military standards required for your application. Ensure the package type matches your PCB design constraints. Validate the manufacturer documentation against current Texas Instruments records following the acquisition.

Selection Notes

Select this component when military-grade reliability and radiation hardness are critical requirements. Compare against standard commercial variants if environmental conditions are less severe. Consider the dual J-K configuration needs versus simpler D-type alternatives. Evaluate power consumption and speed characteristics against system timing requirements. Verify package availability for your manufacturing process.

Part Context

The DM54H72 belongs to the 54H series of bipolar logic devices produced by National Semiconductor. This series is known for high-speed operation and robust performance suitable for demanding environments. National Semiconductor was acquired by Texas Instruments, which now supports these legacy products. The 'DM' designation indicates a military-grade version with stricter quality controls.

Replacement Considerations

Public confirmed substitute part numbers include DM54H72J and DM54H72W. These variants share identical electrical functionality but differ in package style. Verify pin compatibility before substitution. Ensure the replacement meets the same military qualification standards.
