Overview
The LM111JGB is a single-channel differential voltage comparator manufactured by Texas Instruments, housed in an 8-pin Ceramic Dual In-line Package (CDIP). It operates within a supply voltage range of 5V to 36V and features an open-collector output capable of sinking up to 50mA. The device exhibits a typical propagation delay of 200ns and supports a wide operating temperature range from -55°C to +125°C.
Feature Summary
- Integrated strobe input for precise timing control of the output state
- Open-collector output allows flexible interfacing with various logic families
- Differential inputs support high common-mode voltage ranges
Applications
- High-speed pulse generation circuits
- Zero-crossing detection systems
- Window comparator configurations
Procurement Notes
Verify the specific suffix 'JGB' against official Texas Instruments documentation to confirm package type and military-grade specifications. Ensure compatibility with existing PCB footprints for CDIP-8 packages. Confirm availability through authorized distributors as lead times may vary based on production status.
Selection Notes
Select this component when a robust, high-voltage comparator with strobe functionality is required. It is suitable for applications demanding wide supply voltage operation and reliable performance across extreme temperatures. Consider the open-collector output requirements for pull-up resistor selection in the final circuit design.
Part Context
The LM111 series represents a family of general-purpose analog comparators known for their versatility and ruggedness. The LM111JGB variant specifically targets industrial and military environments requiring ceramic packaging for enhanced durability and thermal stability compared to standard plastic packages.
Replacement Considerations
Compatible substitutes include the LM111H/NOPB and LM111JG. Verify pinout compatibility and electrical parameter equivalence before substitution. Ensure that any replacement part meets the same environmental and packaging requirements.
