5962-9755901QRA

Overview

The Texas Instruments 5962-9755901QRA is a military-grade octal buffer and line driver featuring three-state outputs. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an input current (IOL) of up to 64 mA with a maximum supply current of 24,000 µA. The device is housed in a 20-pin Ceramic Dual In-Line Package (CDIP-J). It functions reliably across an extended temperature range from -55 °C to 125 °C and complies with MIL-PRF-38535 Class Q specifications for high-reliability applications.

Feature Summary

• Octal configuration providing eight independent buffered channels
• Three-state output capability for bus-oriented systems
• Military-grade construction compliant with MIL-PRF-38535 Class Q standards
• Robust performance in extreme environmental conditions

Applications

• Harsh environment electronic systems requiring high reliability
• Military aerospace data bus interfaces
• High-speed signal buffering in defense equipment
• Critical control logic isolation in ruggedized platforms

Procurement Notes

Verify that the component explicitly meets MIL-PRF-38535 Class Q requirements before integration. Confirm the package type is CDIP-J with 20 pins. Ensure the operating temperature range covers -55 °C to 125 °C for your specific application. Validate the supply voltage compatibility within the 4.5 V to 5.5 V window. Check for any specific screening or traceability documentation required by your procurement standards.

Selection Notes

Select this part when octal buffering with three-state outputs is required in military or aerospace contexts. It is suitable for designs needing operation at temperatures up to 125 °C. Consider the ceramic package for superior thermal and mechanical stability compared to plastic alternatives. Ensure the system design accommodates the specified 64 mA load current per channel. Verify that the 20-pin CDIP footprint matches the PCB layout constraints.

Part Context

This component belongs to the SN54AS244A family of octal buffers and line drivers. It represents the military-grade variant manufactured under strict quality controls. The device serves as a critical interface element in high-reliability digital circuits. Its design emphasizes robustness and consistent performance in demanding operational environments.

Replacement Considerations

Direct substitutes include other SN54AS244A variants meeting MIL-PRF-38535 Class Q standards. Verify pinout compatibility and electrical parameters before substitution. Ensure the replacement maintains the same CDIP-J package dimensions. Confirm that the alternative source provides equivalent military qualification documentation.
