SN5472J

Flip Flops Overview

The SN5472J is a dual J-K flip-flop from the Texas Instruments TTL/H/L series. It features master-slave operation with complementary outputs and negative edge triggering. The device is housed in a 14-pin ceramic DIP (CDIP-14) package designed for military-grade reliability. It operates within an extended temperature range of -55°C to +125°C, ensuring stable performance in harsh environments.

Flip Flops Feature Summary

• Master-slave architecture prevents race-around conditions during clock transitions
• Complementary output configuration provides both true and inverted logic states
• Military-grade ceramic packaging ensures durability under extreme thermal stress

Flip Flops Applications

• High-reliability military computing systems
• Aerospace data storage registers
• Harsh environment sequential logic control circuits

Flip Flops Procurement Notes

Verify the specific manufacturer source, as Rochester Electronics may distribute this part originally manufactured by Texas Instruments. Confirm the package material is genuine ceramic CDIP-14 rather than plastic alternatives. Ensure the component meets the required -55°C to +125°C operating temperature specifications for your application environment before finalizing procurement.

Flip Flops Selection Notes

Select this component when negative edge-triggered bistable memory is required in high-temperature applications. The dual configuration allows two independent bits of storage per package. Verify that the TTL/H/L input voltage levels match your system logic standards. Consider the larger ceramic footprint compared to modern surface-mount options during PCB layout planning.

Flip Flops Part Context

This component belongs to the standard TTL logic family, specifically utilizing H/L variants for improved performance over basic TTL. The SN54xx series designation indicates military qualification, distinguishing it from commercial SN74xx counterparts. It serves as a fundamental building block for counters and shift registers in legacy or specialized industrial designs requiring radiation and temperature tolerance.

Flip Flops Replacement Considerations

SN5472FC is a compatible alternative offering identical functionality in a flatpack package. SN5472W provides the same electrical characteristics in a hermetic ceramic wide-DIP format. Verify pin compatibility and mounting hole configurations when substituting these packages.
