LM211DT

Overview

The LM211DT is a single-channel general-purpose voltage comparator manufactured by STMicroelectronics in an 8-SOIC surface-mount package. It operates with supply voltages ranging from ±2.5V to ±15V or a single 5V to 30V source. Key electrical specifications include a maximum input offset voltage of 3mV at ±15V, a maximum input bias current of 0.1µA at ±15V, and a typical output current capability of 50mA. The device features a response time of 200ns and supports open collector and emitter outputs compatible with various logic families.

Feature Summary

• Provides low input currents suitable for high-impedance signal sensing applications
• Features open collector and open emitter outputs compatible with RTL, DTL, TTL, and MOS circuits
• Capable of switching output voltages up to +50V with high output current drive
• Operates over a wide supply voltage range from standard op-amp supplies down to single IC logic levels

Applications

• Signal conditioning and waveform generation circuits
• Interface between analog sensors and digital logic systems
• Window comparator configurations for voltage monitoring
• Inverting and non-inverting threshold detection

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure the correct tape-and-reel or cut-tape configuration matches your assembly requirements. Confirm that the component meets RoHS3 compliance standards as specified in the latest product documentation. Cross-reference the part number with authorized distributors to validate authenticity and traceability before finalizing procurement orders.

Selection Notes

Select this component when a general-purpose comparator with TTL-compatible outputs and moderate speed is required. The LM211DT is appropriate for designs needing a wide common-mode input voltage range and direct interfacing with digital logic families without additional level-shifting components. Consider the thermal dissipation capabilities within the SOIC package for power-intensive applications.

Part Context

The LM211DT belongs to the LM211 family of voltage comparators produced by STMicroelectronics. This series is designed to bridge the gap between analog signal processing and digital logic interfaces. The device shares functional similarities with other industry-standard comparators but offers specific output drive characteristics tailored for compatibility with multiple logic technologies including RTL and DTL.
