DS55110AJ/883

Overview

The DS55110AJ/883 is a dual line driver manufactured by National Semiconductor, now part of Texas Instruments. It is designed for military applications and operates over the -55°C to +125°C temperature range. The device features two independent drivers with bipolar technology housed in a ceramic DIP-14 package. It provides high drive capability suitable for demanding environments.

Feature Summary

• Dual independent line driver configuration
• Military-grade reliability qualification
• Extended temperature operation capability

Applications

• Military communication systems
• Aerospace data buses
• Harsh environment signal transmission

Procurement Notes

Verify MIL-STD-883 Class B or higher screening level documentation. Confirm J-subcode authenticity and traceability to original National Semiconductor manufacturing records. Request full test data sheets for electrical parameters and burn-in results prior to acquisition.

Selection Notes

Select this component when dual isolated line driving is required in extreme thermal conditions. Ensure system voltage compatibility with bipolar logic families. Consider package handling requirements for ceramic DIP construction during assembly processes.

Part Context

This part belongs to the SN55110 family of dual line drivers. The /883 suffix indicates compliance with MIL-STD-883 standards. It serves as a ruggedized alternative to commercial grade equivalents for defense and space applications requiring long-term stability.

Replacement Considerations

SN55110J is a direct functional equivalent. Verify pinout compatibility and electrical specifications match before substitution. Check if updated Texas Instruments variants retain identical mechanical dimensions.
