5962-9172701QLA

Overview

The Texas Instruments part number 5962-9172701QLA identifies a specific military-grade variant of the SN54LS373 octal transparent latch. This component is manufactured under the Defense Logistics Agency (DLA) specification and features a hermetically sealed ceramic package designed for high-reliability applications in harsh environments. The device operates with standard LS-TTL logic levels, providing eight D-type latches with three-state outputs. It is qualified to meet rigorous MIL-STD requirements for temperature range and radiation hardness, ensuring stable performance in aerospace and defense systems where standard commercial components would fail.

Feature Summary

• Hermetically sealed ceramic construction for environmental protection
• Qualified to military reliability standards including MIL-STD-883
• Octal configuration with three-state output capability

Applications

• Aerospace data bus interfaces
• Military communication equipment
• Defense system control logic

Procurement Notes

Verify the complete part number against the manufacturer's official cross-reference list to ensure compatibility with existing board designs. Confirm that the supplier provides valid traceability documentation and certification of conformance to the original DLA specifications. Check for any specific handling instructions related to the ceramic package and lead finish. Ensure that the procurement channel is authorized to prevent counterfeit components from entering the supply chain.

Selection Notes

Select this component when design requirements mandate military-grade reliability and radiation tolerance not available in commercial equivalents. Consider the physical dimensions and pinout compatibility if replacing older legacy parts in existing military hardware. Evaluate the thermal management needs associated with the ceramic package compared to plastic alternatives. Verify that the voltage and current specifications align with the rest of the TTL logic family in the system architecture.

Part Context

This part belongs to the broader SN54LS series of logic devices produced by Texas Instruments. The '5962-' prefix indicates it is a direct buy or DLA-managed part number rather than a standard commercial catalog item. It shares functional similarities with other octal latches but differs in packaging and qualification level. The suffix 'QLA' typically denotes specific package style and testing criteria defined by the military specification.

Replacement Considerations

Direct replacements must match the SN54LS373 functionality and maintain the same military qualification level. Verify pin-to-pin compatibility before substitution. Alternative sources may exist through authorized distributors holding DLA stock. Ensure any substitute meets the same environmental and reliability standards required for the application.
