54L74/BCA

Overview

The 54L74/BCA is a dual positive-edge-triggered D flip-flop manufactured by Rochester Electronics. It features independent data (D) and preset (PRE) inputs, along with a clear (CLR) input for both internal circuits. The device includes complementary Q and Q-bar outputs. It is designed for military applications, characterized for operation over the full military temperature range of -55°C to 125°C. The component utilizes a ceramic package suitable for high-reliability environments.

Feature Summary

Dual positive-edge-triggered D flip-flop architecture
Independent preset and clear control inputs
Complementary Q and Q-bar output states
Military-grade temperature characterization

Applications

Military aerospace data storage systems
Space-level digital logic circuits
High-reliability sequential logic design
Defense communication equipment registers

Procurement Notes

Verify the specific suffix and package configuration against the original manufacturer datasheet to ensure compatibility with existing board layouts. Confirm that the military temperature rating aligns with system environmental requirements. Check for any specific handling instructions related to ceramic packages and ensure compliance with relevant quality certifications such as MIL-PRF-38535 if required for the application.

Selection Notes

Select this component when dual D flip-flops are required in harsh environmental conditions. It is suitable for designs needing positive-edge triggering with asynchronous preset and clear functions. Consider the ceramic packaging for superior thermal and mechanical stability compared to plastic alternatives. Ensure the supply chain supports the necessary military qualification standards for the target deployment.

Part Context
