Overview
The LM211DR2G is a single analog comparator manufactured by onsemi, housed in an SOIC-8 surface-mount package. It operates from a single power supply ranging from 5.0 V to 30 V or split supplies up to ±15 V. The device features a complementary output capable of driving loads referenced to ground, VCC, or VEE, supporting logic families such as DTL, RTL, TTL, and MOS. Key electrical specifications include a maximum response time of 200 ns, an input offset voltage of 3 mV, and an operating temperature range of -25 °C to +85 °C.
Feature Summary
- Versatile operation with inputs isolated from system ground while outputs drive loads referenced to various supply rails
- Complementary output structure enables direct interfacing with multiple logic families including DTL, RTL, TTL, and MOS
- High output switching capability allows driving relays, lamps, or solenoids at voltages up to 50 V
Applications
- Driving DTL, RTL, TTL, or MOS logic circuits
- Relay driver applications with strobe capability
- Zero-crossing detector circuits for CMOS logic
- Voltage monitoring and threshold detection systems
Procurement Notes
Verify the specific ordering suffix 'DR2G' corresponds to the SOIC-8 tape and reel packaging configuration. Confirm RoHS compliance status and Pb-Free designation matches project requirements. Ensure the manufacturer part number aligns with the official onsemi datasheet documentation before procurement.
Selection Notes
Select this component when a single-channel comparator with flexible output referencing is required. It is suitable for designs needing to interface with various logic families without additional level shifting. Consider the -25 °C to +85 °C operating range for industrial environments requiring wider thermal tolerance than standard commercial grades.
Part Context
This device belongs to the LM211/LM311 family of single comparators known for their versatility in single or split supply configurations. The LM211 variant specifically supports an extended low-temperature range down to -25 °C compared to the LM311. The DR2G suffix indicates a specific surface-mount packaging option produced by onsemi.
Replacement Considerations
LM311DR2G is a pin-compatible alternative within the same family, though it has a different specified operating temperature range (0 °C to +70 °C). Verify thermal requirements before substitution.
