LM193AJ-QMLV

Overview

The LM193AJ-QMLV is a low power, low offset voltage dual precision comparator manufactured by Texas Instruments. It operates from a single supply ranging from 2.0 VDC to 36 VDC or split supplies of ±1.0 VDC to ±18 VDC. The device features an input common-mode voltage range that includes ground and a differential input voltage range equal to the supply voltage. It provides open-collector outputs compatible with TTL, DTL, ECL, MOS, and CMOS logic systems. The component is qualified under QMLV standards for radiation resistance.

Feature Summary

• Radiation guarantee including Total Ionizing Dose up to 100 krad(Si) and ELDRS free performance
• Low input bias current and low input offset voltage for high precision applications
• Wide single-supply voltage range or dual supply operation capability
• Output voltage compatible with various logic systems including TTL and CMOS

Applications

• Limit comparators
• Simple analog to digital converters
• Pulse, squarewave and time delay generators
• Wide range VCOs
• MOS clock timers

Procurement Notes

Verify the specific ordering suffix matches the required package type and radiation qualification level. Confirm compliance with MIL-STD-883 Method 5005 Group A requirements. Ensure the procurement documentation explicitly states the QMLV certification status. Check for any specific lot traceability requirements mandated by the application environment.

Selection Notes

Select this component when radiation tolerance is critical for the intended mission profile. Consider the low power drain suitable for battery-operated systems. Evaluate the need for precision offset voltage specifications over standard comparator alternatives. Verify compatibility with existing logic families in the design architecture.

Part Context

This part belongs to the LM193 series of dual precision voltage comparators designed for wide voltage range operation. It is specifically engineered for military and space applications requiring high reliability and radiation hardness. The QMLV designation indicates it meets stringent quality and environmental testing standards defined by Texas Instruments for these sectors.

Replacement Considerations

Direct replacements include other LM193QML variants such as LM193AHRLQMLV or LM193AJRQMLV depending on the required package configuration.
