Flip Flops Procurement Notes

Verify the specific suffix designation, such as /883B or /883C, against procurement requirements, as these indicate distinct screening levels under MIL-STD-883. Confirm that the ceramic DIP package matches the mechanical constraints of the target assembly. Ensure that the manufacturer source is authorized to provide components with valid military traceability documentation. Cross-reference the NSN 5962-01-085-6691 to validate part authenticity and compliance with defense supply chain standards before finalizing acquisition.

Flip Flops Selection Notes

Select this component when a hex D-type flip-flop is required for environments exceeding standard commercial temperature limits. The wide 3V to 15V supply range offers flexibility in power design compared to fixed-voltage logic families. Choose this part over plastic packages if hermetic sealing is mandatory for radiation or moisture resistance. Consider the 300 µA quiescent current for power budgeting in battery-operated military applications. Verify compatibility with existing clock and data interface voltages within the specified operational window.

Flip Flops Part Context

This component belongs to the MM54C series, which represents National Semiconductor's line of military-grade CMOS logic devices. The MM54C174 specifically functions as a hex D-type flip-flop, contrasting with other series members like multiplexers or decoders. The /883 suffix denotes adherence to MIL-STD-883 testing standards, differentiating it from commercial MM54C variants. This series is designed for harsh environments, offering superior performance stability compared to standard industrial logic families.

Flip Flops Replacement Considerations

Public confirmed substitute part numbers include MM54C174J/883B and MM54C174J/883C. These variants share identical functional specifications but differ in their MIL-STD-883 screening levels. Ensure the replacement matches the required class certification for the specific application environment.
