SN54LS374J

Flip Flops Overview

The SN54LS374J is an octal D-type edge-triggered flip-flop manufactured by Texas Instruments. It features eight D inputs, eight Q outputs, and a separate clock input. The device includes a three-state output control mechanism for bus-oriented applications. It is housed in a 20-lead ceramic dual-in-line package (CDIP) designed for military-grade reliability. The component operates within a temperature range of -55°C to 125°C and utilizes standard LS TTL logic levels.

Flip Flops Feature Summary

• Octal configuration providing eight independent D-type storage elements within a single integrated circuit
• Edge-triggered operation ensures data capture occurs specifically at the positive transition of the clock signal
• Three-state outputs allow direct connection to system buses without additional buffering hardware
• Military-grade ceramic packaging supports reliable performance across extreme environmental conditions

Flip Flops Applications

• High-reliability military communication systems requiring robust logic processing
• Aerospace computing architectures demanding extended temperature tolerance
• Bus-oriented memory register structures utilizing three-state output capabilities
• Industrial control systems operating in harsh environmental conditions

Flip Flops Procurement Notes

Verify that the received component matches the exact SN54LS374J designation, as suffixes indicate specific package or testing variations. Confirm the ceramic dual-in-line package integrity and pin configuration before installation. Ensure compatibility with existing military-grade supply chain requirements and validate that the unit meets specified operational temperature ranges for the intended application environment.

Flip Flops Selection Notes

Select this component when designing systems requiring octal storage with high noise immunity and wide temperature stability. The LS series offers balanced speed and power consumption suitable for complex logic networks. Consider the three-state feature if bus sharing is required. Verify that the military-grade packaging aligns with the mechanical and thermal constraints of the target assembly compared to commercial alternatives.

Flip Flops Part Context

This part belongs to the SN54xx series, which denotes military-grade specifications distinct from the commercial SN74xx line. The LS suffix indicates Low-power Schottky technology, providing improved switching characteristics. As an octal flip-flop, it serves as a fundamental building block for sequential logic circuits in critical infrastructure where standard commercial components are insufficient.
