LM111WGLQMLV

Overview

The LM111WGLQMLV is a radiation-hardened, QML-V qualified voltage comparator manufactured by Texas Instruments. It features a single channel with an open-collector output and operates within a supply voltage range of 5V to 30V (single) or ±2.5V to ±15V (dual). The device supports an operating temperature range from -55°C to 125°C and is housed in a 10-pin Ceramic Flat Pack (CFP) package.

Feature Summary

• Radiation-hardened design for space applications
• Qualified under the QML-V standard
• Open-collector output configuration

Applications

• Spacecraft instrumentation systems
• Satellite telemetry circuits
• High-reliability industrial control

Procurement Notes

Verify that the specific suffix WGLQMLV corresponds to the required QML-V qualification level and radiation hardness specifications. Confirm the package type is the 10-pin CFP variant. Ensure the supplier provides appropriate documentation for military or aerospace procurement requirements.

Selection Notes

Select this component when radiation tolerance and QML-V compliance are mandatory. It is suitable for designs requiring a single comparator with open-collector outputs. Verify that the input bias current and supply voltage ranges meet the system constraints before integration.

Part Context

This part belongs to the LM111 series of voltage comparators. The LM111WGLQMLV variant is specifically engineered for harsh environments, distinguishing it from commercial grade counterparts through its enhanced reliability standards and radiation resistance capabilities.

Replacement Considerations

Direct replacements must match the QML-V qualification and radiation hardness levels. Standard LM111 variants lack the necessary environmental hardening. Verify pinout compatibility with the 10-pin CFP package before substitution.
