Overview
The LM111J-8LQMLV is a single-channel voltage comparator manufactured by Texas Instruments, designed for military and aerospace applications. It features an open-collector output and operates within a supply voltage range of 5V to 15V. The device exhibits a typical response time of 165μs and supports a wide operating temperature range from -55°C to 125°C. Housed in an 8-pin Ceramic Dual In-Line Package (CDIP), it is suitable for high-reliability environments requiring robust performance under extreme thermal conditions.
Feature Summary
- Military-grade reliability with QML qualification
- Open-collector output configuration
- Wide operating temperature range
Applications
- Aerospace systems
- Military electronics
- High-reliability industrial control
Procurement Notes
Verify the specific suffix LQMLV indicates Qualified Military Life support compliance. Confirm package dimensions match CDIP specifications. Ensure environmental testing data aligns with project requirements. Check for lot traceability documentation. Validate supplier authorization for defense-grade components.
Selection Notes
Select this component when military qualification is mandatory. Consider the open-collector output for flexible interfacing. Evaluate thermal management needs for the -55°C to 125°C range. Compare response times against system timing constraints. Verify package compatibility with existing PCB layouts.
Part Context
This part belongs to the LM111 family of voltage comparators. It shares functional similarities with standard commercial variants but includes enhanced reliability features. The J-8 designation typically refers to the package style and pinout configuration. The LQMLV suffix denotes specific military screening and quality assurance protocols.
Replacement Considerations
LM111J-8/883 is a related variant with similar electrical characteristics. Verify pinout compatibility before substitution. Ensure replacement parts meet the same military qualification standards. Check for any differences in response time or power consumption.
