Overview
The LM111HRLQMLV is a voltage comparator manufactured by Texas Instruments, formerly National Semiconductor. It features an open-collector output and operates within a temperature range of -55°C to 125°C. The device is housed in an 8-pin TO-99 metal package. Key electrical specifications include a maximum average bias current of 0.1 µA at 25°C and a maximum input offset voltage of 4000 µV. It supports a negative supply voltage up to -18 V with a nominal supply of -15 V.
Feature Summary
- Utilizes an open-collector output configuration for flexible interfacing.
Applications
Procurement Notes
Verify the manufacturer designation as Texas Instruments, which acquired National Semiconductor's analog business. Confirm the specific suffix HRLQMLV corresponds to the required military-grade qualification and TO-99 packaging. Ensure compatibility with the specified -55°C to 125°C operating temperature range and 8-pin leaded metal package requirements for your design.
Selection Notes
Select this component when a high-reliability, radiation-hardened capable comparator is needed for extreme environments. The TO-99 metal package provides superior environmental sealing compared to plastic packages. Consider the 4000 µV max offset voltage and low bias current for precision applications requiring stable switching thresholds under varying temperature conditions.
Part Context
This part belongs to the LM111 family of single voltage comparators. The QMLV suffix indicates it meets specific military or aerospace quality standards, often associated with ELDRS-free characteristics in similar National Semiconductor comparator lines. It serves as a ruggedized alternative to commercial grade comparators for defense and space applications.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided data.
