SNJ54ACT374FK

Flip Flops Overview

The SNJ54ACT374FK is an octal edge-triggered D-type flip-flop featuring three-state outputs, manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V and supports a maximum clock frequency of 100 MHz at 5V with 50 pF load capacitance. The device exhibits a typical propagation delay of 10 ns and provides high drive capability with output currents of ±24 mA. Designed for military-grade reliability, it functions across an extended temperature range from -55°C to +125°C. The component is housed in a 20-lead LCCC package.

Flip Flops Feature Summary

• Octal configuration providing eight independent D-type flip-flops with positive-edge triggering.
• Three-state outputs allow direct connection to bus-oriented systems without additional interface hardware.
• Military-grade construction ensures reliable operation under extreme environmental conditions.
• High-speed CMOS technology enables fast switching speeds with low power consumption.

Flip Flops Applications

• Parallel data storage in high-reliability computing systems
• Buffering and registration of data buses in aerospace applications
• Clock distribution networks requiring precise timing control
• Industrial control systems operating in harsh environments

Flip Flops Procurement Notes

Verify the specific suffix FK indicates the 20-lead LCCC ceramic package variant when sourcing. Confirm that the part meets military specifications if required for your application, as commercial variants may differ in temperature rating or testing standards. Ensure compatibility with existing board layouts designed for this specific package footprint. Check for any obsolescence notices or lifecycle status updates directly from the manufacturer before finalizing procurement plans.

Flip Flops Selection Notes

Select this component when designing systems that require robust data latching capabilities under severe thermal stress. The ACT series offers superior speed compared to standard TTL logic while maintaining compatible pinouts. Consider the LCCC package for its hermetic sealing properties if moisture resistance is critical. Evaluate the 100 MHz performance limit against your system's clock requirements to ensure adequate timing margins are maintained during operation.
