Overview
The LM111WG/883 is a single voltage comparator from the LM111QML series, manufactured by Texas Instruments. It features an open collector output and operates within a supply voltage range of ±5 V to ±18 V (single supply 10 V to 36 V). The device has a typical response time of 200 ns and a maximum input offset voltage of 3 mV. It draws 6 mA of operating current and provides 50 mA output sink current. The component is housed in a 10-pin Ceramic Flat Pack (CFP) package with military-grade reliability standards.
Feature Summary
- Military-grade qualification under the LM111QML series for high-reliability applications
- Includes dedicated strobe and input offset voltage adjustment pins for precise control
- Open collector output configuration allows flexible interfacing with various logic families
Applications
- High-reliability aerospace and defense electronic systems
- Precision voltage monitoring circuits requiring low offset
- Industrial control systems with strict environmental tolerance requirements
Procurement Notes
Verify that the specific order includes the /883 suffix, which denotes compliance with MIL-PRF-38534 or similar military quality standards. Confirm the ceramic flat pack package type matches the design footprint. Ensure the QML qualification level meets the project's reliability specifications before finalizing procurement.
Selection Notes
Select this component when military-grade reliability and radiation hardness are required. The LM111WG/883 offers superior stability compared to commercial variants. Consider the CFP package size constraints and the need for external pull-up resistors due to the open collector output structure during circuit design.
Part Context
This part belongs to the LM111 family of general-purpose voltage comparators. The LM111WG/883 variant specifically targets defense and space applications, offering enhanced performance over standard industrial versions. It shares functional similarities with the LM211 and LM311 but differs in temperature range and manufacturing quality controls.
Replacement Considerations
Direct substitutes include other QML-qualified comparators from the same family, such as the LM111WG/883 equivalents from authorized manufacturers. Verify pin compatibility and electrical parameters against the original datasheet before substitution.
