Overview
The LM111 MD8 is a voltage comparator manufactured by Texas Instruments, classified under analog mixed-signal ICs. It operates within a military temperature range of -55°C to 125°C and features a single channel. Key electrical specifications include a maximum input offset voltage of 3 mV at 25°C, a maximum supply voltage of 36 V, and a minimum common-mode input voltage of 0.5 V. The device exhibits a propagation delay time of 0.2 µs and an input bias current of up to 100 nA. Quiescent current per channel ranges from a typical 5.1 mA to a maximum of 6 mA. The output type supports both open collector and open drain configurations.
Feature Summary
- Military-grade reliability with extended operating temperature range
- Strobe functionality for precise timing control
- Input offset voltage adjustment capability
Applications
- High-speed comparison circuits
- Voltage monitoring systems
- Logic level translation
Procurement Notes
Verify the specific die or wafer lot status as indicated by the MD8 suffix. Confirm that the component meets all military qualification requirements for the intended application environment. Ensure compatibility with the required package group options such as CDIP, CFP, or TO-99 when designing the final assembly.
Selection Notes
Select this component when military-grade performance and wide temperature operation are required. Consider the high quiescent current consumption compared to modern low-power alternatives. Verify that the open collector/drain output interface matches the system logic levels and pull-up requirements.
Part Context
This part belongs to the LM111 family of voltage comparators. It shares functional similarities with other military-grade variants like the LM111H/883 but differs in packaging and specific test conditions. The MD8 designation typically refers to a specific die or wafer form factor sold for custom integration or specialized packaging solutions.
Replacement Considerations
Public confirmed substitute part numbers include LM111-MW8, LM111 MW8, and LM111 MD8 variants. Cross-reference with LM111H/883 for pin-compatible alternatives in standard packages.
