Overview
The LM211P is a single differential comparator manufactured by Texas Instruments, housed in an 8-pin SOIC package. It features a strobe input for output control and operates within a temperature range of -40°C to 85°C. The device supports a wide supply voltage range and includes internal compensation for stability.
Feature Summary
- Integrates a strobe function to enable or disable the output state on demand
- Provides high-speed differential comparison with internal frequency compensation
- Supports single or dual power supply configurations for flexible system integration
Applications
- Voltage threshold detection circuits
- Zero-crossing detectors
- Logic interface adapters
Procurement Notes
Verify the specific suffix 'P' confirms the SOIC-8 package variant. Confirm RoHS compliance status through the official datasheet revision history. Ensure the operating temperature range meets the environmental requirements of the target application before finalizing procurement.
Selection Notes
Select this component when a strobed output is required for noise immunity or synchronization. Compare input offset voltage and propagation delay against TLV1391 for modern low-power alternatives. Verify pin compatibility if replacing legacy designs with newer comparator families.
Part Context
The LM211 belongs to the standard LM211/LM311 family of comparators. The 'P' suffix denotes the plastic small-outline integrated circuit (SOIC) package. This series is widely used in industrial and commercial applications requiring reliable voltage comparison with external control capabilities.
Replacement Considerations

FAQ
What is the function of the strobe input?
The strobe input allows the user to enable or disable the comparator output, preventing false triggering during unstable conditions.
Is the LM211 internally compensated?
Yes, the LM211 includes internal frequency compensation to ensure stability without requiring external components.
