Overview
The 54F374/BRA is a high-speed Schottky (F-Series) octal D-type flip-flop manufactured by Rochester Electronics. It features true outputs and operates within a supply voltage range of 4.5 V to 5.5 V. The device is housed in a 20-lead CDFP (Ceramic Dual Flat Pack) package, suitable for military and aerospace applications requiring radiation hardness and reliability. It includes clocked data storage with positive-edge triggering and is designed for bus-oriented systems.
Feature Summary
- Octal D-type flip-flop architecture providing eight independent data storage elements
- High-speed Schottky logic technology ensuring fast propagation delays
- True output polarity for direct signal interfacing without inversion
- Positive-edge clock triggering mechanism for precise timing control
Applications
- Military-grade digital data storage systems
- Aerospace bus-oriented architectures
- High-reliability industrial control registers
- Radiation-hardened electronic subsystems
Procurement Notes
Verify the specific revision code and manufacturing date code upon order confirmation. Confirm that the ceramic flat pack package meets your board layout requirements. Ensure compatibility with 5V logic levels in your system design. Request full traceability documentation if required for your quality standards.
Selection Notes
Select this component when high-speed performance combined with ruggedized packaging is required. The F-series offers faster switching than standard LS logic. The ceramic package provides superior environmental protection compared to plastic variants. Verify pinout compatibility with existing designs before integration.
Part Context
This part belongs to the SN54F374 family of octal D-type flip-flops. It is a military-grade version characterized for extended temperature ranges. Rochester Electronics sources these components through authorized channels or qualified reproduction programs. The device serves as a fundamental building block for sequential logic circuits in demanding environments.
Replacement Considerations
Direct substitutes include other SN54F374 variants from different manufacturers. Check for equivalent ceramic flat pack packages. Verify that replacement parts meet the same voltage and speed specifications. Ensure pin-to-pin compatibility for seamless integration.
