Overview
The LM211DE4 is a single high-speed comparator manufactured by Texas Instruments, housed in an 8-SOIC surface-mount package. It operates with a supply voltage range of 3.5V to 30V (single) or ±1.75V to ±15V (dual). Key electrical specifications include a maximum input offset voltage of 3mV at ±15V, a typical output current of 50mA, and a maximum static current of 6mA. The device supports DTL, MOS, open-collector, open-emitter, RTL, and TTL outputs, functioning within a temperature range of -40°C to 85°C.
Feature Summary
- Features a wide operating supply voltage range supporting both single and dual power configurations.
- Provides versatile output compatibility with standard logic families including DTL, MOS, and TTL.
- Delivers high-speed performance suitable for demanding signal processing applications.
Applications
- High-speed comparing circuits
- Voltage threshold detection systems
- Waveform generation and shaping
Procurement Notes
Verify the specific suffix 'E4' indicates lead-free compliance during procurement. Confirm the 8-SOIC package dimensions match the design footprint. Ensure the operating environment stays within the specified -40°C to 85°C range. Check for RoHS3 certification status if required by regulatory standards. Validate supply voltage limits against the application's power rails.
Selection Notes
Select this component when a general-purpose, high-speed comparator is required. Consider the 50mA output drive capability for direct interface needs. Evaluate the 3mV offset voltage specification for precision requirements. Compare the 8-SOIC package against available board space constraints. Assess the wide supply voltage flexibility for system power architecture compatibility.
Part Context
The LM211DE4 belongs to the LM111/LM211/LM311 family of comparators from Texas Instruments. This series is known for robust performance across industrial and commercial environments. The DE4 designation specifically identifies the tape-and-reel variant of the 8-SOIC package, facilitating automated assembly processes.
Replacement Considerations
The LM211D serves as the primary equivalent part number. Verify pinout and electrical specifications match before substitution. Ensure the replacement maintains the same 8-SOIC package form factor.
