SN54LS173AJ

Flip Flops Overview

The SN54LS173AJ is a 4-bit D-type register featuring totem-pole 3-state outputs, manufactured by Texas Instruments. It operates within a supply voltage range of 4.75 V to 5.25 V and supports a propagation delay of 30 ns. The component provides an output drive capability of 24 mA (low) and -2.6 mA (high). It is housed in a 16-CDIP package with dimensions of 0.300 inches (7.62 mm). Designed for military specifications, it functions across a temperature range of –55°C to 125°C.

Flip Flops Feature Summary

• Features 4-bit D-type flip-flops with positive edge triggering
• Includes totem-pole 3-state outputs for bus driving applications
• Capable of driving highly capacitive loads

Flip Flops Applications

• Military electronic systems requiring wide temperature operation
• Bus-oriented memory register implementations
• High-capacitance load driving circuits

Flip Flops Procurement Notes

Verify the specific ordering suffix 'AJ' against the manufacturer's current datasheet to confirm package type and temperature grade. Ensure compatibility with existing PCB footprints for the 16-CDIP configuration. Confirm that the 3-state output logic levels match the system requirements before finalizing procurement.

Flip Flops Selection Notes

Select this component when military-grade temperature stability from –55°C to 125°C is required. Choose the SN54LS173AJ over commercial variants if the application involves high capacitive loading or needs robust bus driving capabilities. Verify that the TTL input type aligns with the source logic family.

Flip Flops Part Context

This part belongs to the SN54LS173A series of 4-bit registers with 3-state outputs. It is designed for use in environments where standard commercial components may fail due to extreme temperatures. The device serves as a fundamental building block for digital data storage and transfer in specialized hardware.

Flip Flops Replacement Considerations

The SN54LS173AN is a related variant but typically lacks the full military temperature range certification found in the AJ suffix version. Verify pinout compatibility and electrical characteristics before substituting.
