54F280/BDA

Overview

The 54F280/BDA is a 9-bit parity generator and checker belonging to the F/FAST logic series. It features complementary outputs and operates within a temperature range of -55 °C to +125 °C. The device utilizes TTL logic levels and is housed in a CDFP14 ceramic flatpack package with 14 terminals. Key electrical parameters include a maximum propagation delay of 12 ns, a load capacitance of 50 pF, and a maximum supply current (ICC) of 35 mA.

Feature Summary

• Performs 9-bit parity generation and checking functions
• Provides complementary output signals for data verification
• Operates reliably across extended industrial temperature ranges

Applications

• Data bus integrity monitoring systems
• Industrial control network communication interfaces
• High-reliability computing memory subsystems

Procurement Notes

Verify the specific manufacturer origin, as this component may be sourced from NXP or Rochester Electronics depending on production lot. Confirm the package type matches the required CDFP14 ceramic flatform specification. Ensure the operating temperature rating aligns with the intended environmental conditions before integration into final designs.

Selection Notes

Select this component when a high-speed, 9-bit parity solution is required for harsh environments. The F/FAST series offers faster switching speeds compared to standard TTL counterparts. The ceramic flatpack package provides superior thermal stability and mechanical robustness suitable for military or aerospace applications where plastic packages are unsuitable.

Part Context

This part belongs to the widely used 54-series military-grade logic family, ensuring compatibility with existing high-reliability digital systems. The 54F280 variant specifically addresses the need for rapid error detection in parallel data transmission paths. Its design supports long-term availability requirements for legacy infrastructure maintenance.

Replacement Considerations

Direct substitutes include the MC54F280JD and 54F280B variants. Verify pinout compatibility and ensure the replacement maintains the same CDFP14 ceramic package dimensions and thermal characteristics.
