Overview
The 54H78FM is a dual D-type flip-flop element manufactured by Rochester Electronics, LLC. It belongs to the 54H series of military-grade logic components, designed for high-reliability applications. The device features two independent functional units within a single package, each capable of storing one bit of data. It utilizes a metal case surface mount package (MAS) suitable for harsh environments. The component operates as a synchronous storage element, providing complementary outputs for each flip-flop function. This part is intended for use in systems requiring robust digital signal processing and memory retention under extreme conditions.
Feature Summary
- Dual independent D-type flip-flop functions integrated into a single unit
- Military-grade construction utilizing a metal case surface mount package
- Complementary output configuration for each flip-flop element
- Guaranteed performance meeting original OEM specifications
Applications
- Military aerospace electronic systems
- Defense logistics agency hardware
- High-reliability digital signal processing circuits
- Harsh environment data storage modules
Procurement Notes
Verify that the received component matches the 54H78FM designation and packaging type. Confirm compliance with original OEM datasheet requirements through testing using factory programs or Rochester-developed solutions. Ensure the metal case surface mount package integrity is intact. Validate that the product meets or exceeds the specified performance criteria for military applications before integration.
Selection Notes
Select this component when dual-bit storage is required in a compact military-grade form factor. The 54H series offers higher speed than standard 5400 series parts while maintaining radiation hardness and wide temperature tolerance. Consider the MAS package for superior thermal dissipation and mechanical stability compared to plastic alternatives. Ensure system design supports the specific voltage and current requirements of the 54H logic family.
Part Context
Rochester Electronics, LLC supplies this component as part of its comprehensive lifecycle support program. The company is authorized by over 70 leading semiconductor manufacturers to provide continuous availability of obsolete and end-of-life semiconductors. The 54H78FM represents a continuation of supply for critical defense and aerospace applications where original equipment manufacturer production has ceased.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Users should consult official cross-reference guides or contact Rochester Electronics directly for verified equivalents.
