SNJ54HC175J

Flip Flops Overview

The SNJ54HC175J is a military-grade quadruple D-type flip-flop with positive-edge triggering and an asynchronous clear input, manufactured by Texas Instruments. It utilizes the HC (High-speed CMOS) logic family technology to provide high-speed operation while maintaining low power consumption characteristics typical of CMOS devices. The component is housed in a 16-lead ceramic dual-in-line package (CDIP), designed for robust performance in harsh environments. It operates within a supply voltage range of 2V to 6V and supports a wide operating temperature range from -55°C to +125°C, ensuring reliability in demanding applications.

Flip Flops Feature Summary

• Quadruple D-type flip-flops with positive-edge clock triggering
• Asynchronous active-low clear input for immediate state reset
• Military-grade construction with ceramic dual-in-line packaging
• Wide supply voltage and temperature operational ranges

Flip Flops Applications

• Military aerospace data storage systems
• Industrial control register arrays
• High-reliability shift register circuits
• Avionics timing and sequencing logic

Flip Flops Procurement Notes

Verify the specific ordering suffix 'J' confirms the ceramic DIP package and military grade qualification. Ensure the datasheet matches the current revision for electrical parameters. Confirm availability through authorized distributors as military parts may have restricted supply chains. Check for compliance with export control regulations due to the military designation.

Flip Flops Selection Notes

Select this component when military-grade reliability and wide temperature tolerance are required. Compare propagation delay specifications against system timing requirements. Verify pin compatibility if replacing older TTL or LS series components. Consider the higher cost associated with ceramic packaging compared to plastic alternatives.

Flip Flops Part Context

This part belongs to the SN54HCxx series of high-speed CMOS logic devices. The 'SNJ' prefix indicates a military-grade device with a ceramic package, distinguishing it from commercial variants like SN54HC175. It is functionally equivalent to other quadruple D-flip-flops but offers enhanced environmental resilience suitable for defense and space applications.
