Overview
The LM111H is a single-channel analog comparator manufactured by Texas Instruments, housed in an 8-pin TO-99 metal can package. It operates within a supply voltage range of 5 V to 36 V and draws a typical quiescent current of 6 mA per channel. The device features an open-collector output capable of sourcing up to 50 mA. Key electrical specifications include a maximum input offset voltage of 3 mV, an input bias current of 100 nA, and a propagation delay of 200 ns. It supports differential inputs and functions across an extended temperature range from -55 °C to +125 °C.
Feature Summary
- Provides general-purpose voltage comparison with high-speed response characteristics suitable for demanding applications.
- Features an open-collector output stage that allows flexible interfacing with various logic families and load types.
- Designed for operation over an extended industrial temperature range, ensuring reliability in harsh environments.
Applications
- Overvoltage and undervoltage protection circuits
- Window detector configurations
- Zero-crossing detection systems
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official documentation to confirm pinout compatibility and environmental ratings. Ensure the selected variant matches the required thermal performance and packaging constraints for the target application design.
Selection Notes
Select this component when a single-channel comparator with low offset voltage and high output drive capability is required. Consider the TO-99 package for hermetic sealing needs and evaluate the 200 ns propagation delay against system timing requirements.
Part Context
The LM111H belongs to the LM111 series of precision comparators. This family is characterized by its robust performance in military and industrial sectors, offering stable operation across wide temperature ranges and providing reliable signal switching for critical control loops.
Replacement Considerations
Consult official substitution guides for equivalent parts such as the LM111H/NOPB or other LM111 variants. Verify functional compatibility regarding pin assignments and electrical parameters before implementation.
