LM211MDREP

Overview

The LM211MDREP is a single-channel standard comparator manufactured by Texas Instruments, housed in an 8-SOIC surface-mount package. It operates on 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 and a maximum input bias current of 0.1µA at ±15V. The device supports DTL, MOS, open-collector, open-emitter, RTL, and TTL output types with a typical output current of 50mA. It functions within a temperature range of -55°C to 125°C and has a maximum static current consumption of 6mA.

Feature Summary

• Supports multiple logic interface compatibility including DTL, MOS, RTL, and TTL via versatile output configurations.
• Features low input bias current characteristics suitable for high-impedance signal sensing applications.
• Provides robust operation across extended industrial temperature ranges up to 125°C.

Applications

• General-purpose analog signal comparison circuits
• Voltage threshold detection systems
• Logic interface conversion between different technology families

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct package type and tape/reel configuration. Confirm that the component meets RoHS3 compliance requirements for your assembly process. Cross-reference the manufacturer part number with authorized distributor listings to validate authenticity and traceability before finalizing procurement orders.

Selection Notes

Select this component when a single-channel comparator with wide supply voltage flexibility and multi-logic output compatibility is required. Consider the 8-SOIC package dimensions for PCB layout constraints. Evaluate the input offset voltage and bias current specifications against the precision requirements of the target application circuit to ensure adequate performance margins.
