JM38510/32403SSA

Overview

The JM38510/32403SSA is a space-grade octal buffer and line driver manufactured by Texas Instruments. It features three-state outputs and operates within a supply voltage range of 4.5 V to 5.5 V. The device is housed in a 20-pin Ceramic Flat Pack (CFP) package designated as W. It supports an extended operating temperature range from -55 °C to 125 °C, ensuring reliability in harsh environments.

Feature Summary

• Octal configuration providing eight independent buffer channels
• Three-state output capability for bus-oriented applications
• Space-qualified design for radiation-hardened environments

Applications

• Spacecraft signal buffering
• Military communication systems
• High-reliability data transmission buses

Procurement Notes

Verify the specific suffix SSA confirms the CFP(W) package and space-grade qualification. Confirm lead times and availability directly with authorized distributors or Texas Instruments, as military/aerospace components often have restricted supply chains. Ensure compliance with relevant export control regulations when procuring this component.

Selection Notes

Select this component when eight buffered channels with tri-state control are required in a compact flat pack format. It is suitable for designs needing operation across wide temperature extremes and high radiation tolerance. Compare pinout compatibility with existing board layouts before integration.

Part Context

This part belongs to the SN54LS24x family of octal buffers. The JM38510 prefix indicates it meets MIL-STD-38510 standards for high-reliability electronic devices. It serves as a robust interface solution for critical aerospace and defense applications where standard commercial parts are insufficient.

Replacement Considerations

Check for direct cross-reference part numbers such as SN54LS244 variants if package differences are acceptable. Verify that any substitute maintains the same 20-pin CFP footprint and space-grade radiation specifications.
