JM54AC125SCA-RH

Overview

The JM54AC125SCA-RH is a quad bus driver from the AC series, manufactured by National Semiconductor. It features four non-inverting 1-bit drivers with three-state outputs, housed in a 14-pin ceramic dual in-line package (CDIP). Designed for military temperature ranges, it operates between -55°C and 125°C. The device utilizes CMOS technology and supports supply voltages of 3.3V or 5V. Propagation delay is typically 11 ns at nominal supply. It provides high-speed data handling capabilities suitable for demanding applications.

Feature Summary

• Four non-inverting bus drivers with independent three-state control
• Military-grade reliability with extended temperature range operation
• CMOS technology ensuring low power consumption and high noise immunity

Applications

• High-speed data handling systems
• Military electronic equipment

Procurement Notes

Verify the specific ordering suffix to confirm the exact package variant and lead time requirements. Ensure compatibility with existing system voltage levels and thermal management strategies. Confirm that the ceramic package meets the mechanical constraints of the target assembly. Check for any specific qualification standards required by the end application.

Selection Notes

Select this component when a quad bus driver with three-state outputs is required for military or high-reliability environments. Consider the CDIP package size and pin configuration against available board space. Evaluate the propagation delay specifications against the system timing requirements. Ensure the supply voltage range aligns with the design's power architecture.

Part Context

This part belongs to the 54AC family of logic devices, which are designed for high-speed performance and wide operating temperature ranges. The 'JM' prefix indicates military grade qualification. The 'SCA' suffix denotes the specific ceramic DIP package style. This series is commonly used in aerospace and defense applications where robustness is critical.

Replacement Considerations

Check for direct equivalents within the 54AC series from other manufacturers. Verify pinout compatibility if substituting with similar quad bus drivers. Ensure the replacement part meets the same military temperature and radiation hardness requirements if applicable.
