Overview
The 5962R9673801VXA is a quad comparator from the LM139AxQMLV family, manufactured by Texas Instruments (formerly National Semiconductor). It features a 14-pin Ceramic Flat Pack (CFP) package. The device operates with supply voltages up to ±15V or 30V single supply. Key electrical parameters include an input bias current of 0.1 µA and a maximum input offset voltage of 2000 µV. It is designed for low power and low offset voltage applications.
Feature Summary
- Quad differential comparator configuration
- Radiation hardening via Single Event Transient (SET) data verification
- Low input bias current design
- Low offset voltage performance
Applications
- Military aerospace systems requiring radiation tolerance
- Precision analog signal processing
- Low power comparator circuits
- High reliability industrial control
Procurement Notes
Verify the manufacturer origin as Texas Instruments, noting its acquisition of National Semiconductor. Confirm the specific suffix VXA indicates the ceramic flat pack variant. Ensure compliance with military specifications if required for the intended application. Check for recent process change notifications regarding packaging or material composition.
Selection Notes
Select this component when radiation hardness against single event transients is critical. Compare input offset voltage requirements against the 2000 µV maximum. Consider the 14-pin CFP package constraints for board layout. Evaluate power consumption needs against the low bias current characteristics.
Part Context
This part belongs to the LM139AxQMLV series, which are low power, low offset voltage quad comparators. The 5962R9673801VXA designation specifically identifies the QMLV qualified version in the CFP package. It is distinct from plastic package variants like the 5962R9673802VXA.
Replacement Considerations
Public confirmed substitutes include other LM139AxQMLV variants within the same radiation-hardened family. Verify pinout compatibility and package dimensions before substitution. Cross-reference with 5962R9673802VXA only if plastic packaging is acceptable.
