JM54ACT74BDA-RH

Overview

The JM54ACT74BDA-RH is a dual D-type flip-flop belonging to the ACT series, manufactured by National Semiconductor. It features independent data (D), clock (CLK), preset (PRE), and clear (CLR) inputs for each flip-flop. The device utilizes complementary outputs (Q and Q-bar). It operates within a supply voltage range of 2.0V to 6.0V. The component is housed in a 16-lead CERDIP package with a body width of 0.300 inches. It supports an operating temperature range from -55°C to 125°C.

Feature Summary

• Dual D-type flip-flop architecture with independent control inputs
• Complementary output configuration for versatile logic interfacing
• Wide supply voltage operation capability
• High-temperature ceramic packaging for harsh environments

Applications

• Military aerospace systems requiring high reliability
• Industrial control units operating in extreme temperatures
• Data storage and shift register circuits

Procurement Notes

Verify the specific suffix BDA-RH against official datasheets to confirm package type and environmental rating. Ensure compatibility with MIL-STD requirements if applicable. Confirm manufacturer origin as National Semiconductor or authorized successor entities. Validate pinout alignment with standard 16-lead CERDIP specifications before integration into existing designs.

Selection Notes

Select this component when dual D-flip-flops are required in high-reliability military or industrial applications. Consider the wide temperature range and ceramic packaging for durability. Compare performance metrics such as propagation delay and power consumption against other ACT series variants. Ensure the supply voltage range matches the system design constraints.

Part Context

This part belongs to the 54ACT family, which offers high-speed CMOS logic performance comparable to TTL but with lower power consumption. The 54-series designation typically indicates military-grade qualification and extended temperature ranges compared to the commercial 74-series equivalents.

Replacement Considerations

Check for equivalent parts from Texas Instruments or Rochester Electronics. Verify pin compatibility and electrical characteristics. Ensure the replacement meets the same environmental and reliability standards.
