MM54C74W/883

Flip Flops Overview

The MM54C74W/883 is a dual D-type flip-flop manufactured by National Semiconductor (now Texas Instruments). It features CMOS technology housed in a ceramic flatpack package. The device includes separate clock inputs and preset/clear controls for each flip-flop. It supports asynchronous data input and complementary outputs. The component is designed for military specifications, ensuring reliability under extreme conditions.

Flip Flops Feature Summary

• Dual D-type flip-flop configuration with independent control
• Ceramic flatpack construction for durability
• Asynchronous preset and clear functionality
• Complementary output states

Flip Flops Applications

• Military aerospace systems requiring high reliability
• Data storage registers in harsh environments
• Shift register applications in defense electronics
• Timing and synchronization circuits in space-grade equipment

Flip Flops Procurement Notes

Verify the manufacturer source carefully as National Semiconductor is now part of Texas Instruments. Confirm the specific suffix 'W/883' indicates the correct ceramic flatpack package and MIL-STD-883 compliance. Check for lot traceability and quality certifications required for military procurement. Ensure compatibility with existing board layouts due to the specific flatpack footprint.

Flip Flops Selection Notes

Select this component when a dual D-flip-flop is needed in a ruggedized ceramic package. Consider it for designs requiring MIL-STD-883 qualification. Evaluate thermal management needs due to the ceramic housing. Compare pinout compatibility with other C74 series devices if upgrading or replacing existing designs. Verify voltage levels match system requirements.

Flip Flops Part Context

This part belongs to the MM54Cxx series of military-grade CMOS logic devices. It is functionally similar to commercial C74 series but with enhanced environmental ratings. The 'W' denotes the flatpack package style. The '/883' signifies adherence to MIL-STD-883 testing standards. It is distinct from plastic packaged variants like the MM54C74N.
