Overview
The Texas Instruments part number 5962-9322001QRA designates a specific military-grade variant of the SN74ALS125 quad buffer and line driver. This component is manufactured under the Defense Logistics Agency (DLA) contract system, indicated by the '5962' prefix. It features four independent non-inverting buffers with separate output enable controls. The device operates within a standard voltage range typical for ALS logic families and is qualified for extended temperature ranges suitable for harsh environments.
Feature Summary
- Military-grade qualification ensuring reliability in demanding operational conditions
- Quad configuration providing four independent non-inverting buffer channels
- Individual output enable inputs allowing precise control over signal transmission
Applications
- High-reliability aerospace avionics systems
- Military communication equipment requiring robust signal buffering
- Industrial control systems operating in extreme environmental conditions
Procurement Notes
Verify the DLA contract status and ensure the supplier provides valid traceability documentation. Confirm that the received components match the exact MIL-spec requirements for your application. Check for proper handling procedures due to the sensitive nature of military-grade electronics.
Selection Notes
Select this component when military qualification is mandatory for the project. Ensure compatibility with existing ALS logic family standards. Verify that the package type and pinout meet the board layout specifications. Consider the extended temperature range capabilities if the environment exceeds commercial limits.
Part Context
This part belongs to the SN74ALS series of high-speed Schottky TTL logic devices. The 5962 prefix indicates it is a direct buy item from the Defense Logistics Agency catalog. It serves as a ruggedized version of commercial logic buffers, designed for longevity and performance stability in critical applications.
Replacement Considerations
Direct replacements must be verified against the DLA cross-reference list. Equivalent parts should maintain the same pinout and electrical characteristics. Ensure any substitute also holds the necessary military qualifications if required by the system design.
