SNJ54ABT374J

Flip Flops Overview

The SNJ54ABT374J 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 150 MHz under specified load conditions. The device exhibits a propagation delay of 6.6 ns and provides high drive capability with output currents of -32 mA (high) and 64 mA (low). Designed for military-grade reliability, it functions across an extended temperature range from -55°C to +125°C. The component utilizes a 20-lead Ceramic Flat Package (CFP) for through-hole mounting.

Flip Flops Feature Summary

• Octal configuration providing eight independent D-type edge-triggered flip-flops in a single package
• Three-state outputs enabling direct bus-driven connections without external buffers
• Military-grade construction supporting operation in extreme environmental temperatures
• High-speed performance with low propagation delay suitable for demanding digital systems

Flip Flops Applications

• Military aerospace avionics and communication systems
• Industrial control systems requiring wide temperature tolerance
• High-speed data acquisition and storage registers
• Buffer and register applications in harsh environment electronics

Flip Flops Procurement Notes

Verify the specific suffix J indicates the ceramic flat package variant when sourcing. Confirm that the component meets all required military specifications and environmental certifications for your application. Check current availability as specialized military parts may have limited stock or longer lead times compared to commercial equivalents. Ensure compatibility with existing board layouts designed for the 20-lead CFP footprint.

Flip Flops Selection Notes

Select this component when military-grade reliability and wide temperature operation are mandatory. The SNJ54ABT374J offers higher drive strength than standard logic families, reducing the need for additional buffering. Consider the physical size and weight of the ceramic package against space constraints. Compare performance metrics against lower-cost commercial alternatives if environmental conditions allow.

Flip Flops Part Context

This part belongs to the SN54/74ABT series of advanced bipolar transistor-transistor logic devices. The ABT family combines the speed of AS logic with low power consumption characteristics. The SNJ prefix denotes a military-grade version manufactured by Texas Instruments, ensuring strict adherence to quality standards for defense and aerospace applications.

Flip Flops Replacement Considerations

SNJ54ACT374J: Similar function but slower speed and different electrical characteristics. SNJ54F374J: Faster switching but significantly higher power consumption. SNJ54LS374J: Lower speed and reduced drive current. Verify pinout and electrical parameters before substituting.
