Overview
The 54H72J/B is an AND-gated JK master-slave flip-flop manufactured by Rochester Electronics. It belongs to the 54H series of high-speed TTL logic devices, designed for robust performance in demanding environments. The component features a master-slave architecture with an additional AND gate input to control clocking, providing precise data synchronization capabilities. It is housed in a ceramic dual in-line package suitable for military and aerospace applications requiring high reliability and wide temperature tolerance.
Feature Summary
- Integrates a JK master-slave flip-flop with an AND-gated clock input for controlled state transitions
- Constructed using high-speed TTL technology for rapid switching performance
- Designed for operation across extended temperature ranges typical of military specifications
Applications
- Military-grade digital logic circuits
- Aerospace data storage systems
- High-reliability synchronous counters
Procurement Notes
Verify authenticity through official manufacturer channels or authorized distributors. Confirm lot traceability and compliance with relevant military standards such as MIL-PRF-38534 if applicable. Request detailed test reports to ensure device integrity and parameter consistency before integration into critical systems.
Selection Notes
Select this component when high-speed synchronous logic with gated clocking is required in harsh environments. Ensure compatibility with existing TTL voltage levels and interface requirements. Consider thermal management needs due to the power characteristics inherent to high-speed TTL families.
Part Context
Rochester Electronics specializes in sourcing and distributing obsolete and hard-to-find electronic components, including legacy military and industrial parts. The 54H72J/B represents their capability to provide continuity for critical systems relying on discontinued original equipment manufacturer products.
Replacement Considerations
Direct substitutes include other 54H-series JK flip-flops from Texas Instruments or equivalent military-grade sources. Verify pinout compatibility and electrical parameters against the original design specifications before substitution.
