Procurement Notes

Verify the manufacturer traceability and lot history when sourcing this component, as it is a specialized military-grade part. Confirm that the 16-CDIP package dimensions match your existing board layout constraints. Ensure that the supply voltage requirements align with your system's power distribution network. Request full datasheet documentation to validate the specific JRQMLV suffix characteristics against your design specifications before finalizing procurement.

Selection Notes

Select this component when designing systems that require robust logic performance under harsh environmental conditions. The ACT series offers speed and power consumption benefits suitable for complex digital circuits. Consider the 16-CDIP package if through-hole mounting or specific thermal management strategies are required. Verify compatibility with existing CMOS logic families in your design architecture to ensure proper interfacing and signal levels.

Part Context

This part belongs to the 54ACT175 family of quad D-type flip-flops. The 54 prefix indicates military grade qualification, while ACT denotes advanced CMOS technology. The JRQMLV suffix typically signifies specific packaging and testing standards for defense applications. National Semiconductor, now part of Texas Instruments, produced this line for high-reliability sectors.

Replacement Considerations

Check for direct cross-reference from Texas Instruments, which acquired National Semiconductor. Verify pinout compatibility and electrical parameters against other 54ACT175 variants. Ensure any substitute maintains the same CDIP package form factor and military temperature rating.
