Flip Flops datasheet and documents for SNJ54LS173AFK
Flip Flops Overview
The SNJ54LS173AFK is a military-grade 4-bit D-type register featuring 3-state outputs, manufactured by Texas Instruments. It operates within a supply voltage range of 4.75 V to 5.25 V and utilizes positive edge-triggered flip-flops. The component is housed in a 20-lead LCC package with dimensions of 8.89 mm length. It supports unidirectional data flow and includes dual output enable controls. The device is characterized for reliable operation across the full military temperature range of -55°C to +125°C.
Flip Flops Feature Summary
- Military-grade reliability characterized for extreme environmental conditions
- Four-bit storage capability with tri-state output control
- Positive edge triggering mechanism for precise timing synchronization
Flip Flops Applications
- Aerospace avionics data processing systems
- Defense communication equipment registers
- Industrial control systems requiring wide temperature tolerance
Flip Flops Procurement Notes
Verify that the specific suffix 'FK' corresponds to the 20-LCCC package configuration as documented in official Texas Instruments datasheets. Ensure procurement channels provide traceability documentation suitable for military specifications. Confirm that the component meets the required -55°C to +125°C operational range for your specific application environment before finalizing orders.
Flip Flops Selection Notes
Select this component when military-grade temperature stability and high-reliability performance are mandatory. The SNJ54LS173AFK is appropriate for applications requiring 4-bit storage with bus-compatible 3-state outputs. Consider the 20-lead LCC package constraints for PCB layout. This part is distinct from commercial variants due to its extended temperature characterization and ruggedized construction.
Flip Flops Part Context
This component belongs to the SN54/74LS173 family of 4-bit D-type registers. The SNJ prefix indicates a military-grade version, while the LS series denotes low-power Schottky logic technology. It serves as a fundamental building block for sequential logic circuits in high-reliability digital systems, offering stable data retention and controlled output states.
Flip Flops Replacement Considerations
The SN54LS173AFK is a direct functional equivalent. Commercial versions such as SN74LS173AD differ in temperature range and packaging. Verify pin compatibility and electrical characteristics against current design requirements when substituting.
