Overview
The LM311DR2G is a single general-purpose analog comparator manufactured by onsemi in an SOIC-8 surface-mount package. It operates from a single power supply of 5.0 V to 30 V or split supplies up to ±15 V. Key electrical characteristics include a response time of 200 ns, a maximum input offset voltage of 7.5 mV at +25 °C, and a positive supply current of 2.4 mA typical. The device features complementary outputs capable of driving loads referenced to ground, VCC, or VEE, with the ability to switch voltages up to 50 V at currents up to 50 mA.
Feature Summary
- Supports operation from single or split power supplies for versatile system integration
- Outputs can drive DTL, RTL, TTL, or MOS logic families directly
- Capable of switching high voltages and currents suitable for relays and solenoids
- Includes strobe capability for output control
Applications
- Driving relays, lamps, or solenoids
- Zero-crossing detector circuits
- Crystal oscillator configurations
- IGBT driver interfaces
Procurement Notes
Verify the specific suffix 'DR2G' against the manufacturer's ordering information to confirm the SOIC-8 package and tape-and-reel shipping format. Confirm RoHS compliance status as indicated in the datasheet. Check for discontinuation notices regarding the LM311 series before finalizing procurement plans.
Selection Notes
Select this component when a single-channel comparator with flexible output referencing is required. Ensure the application stays within the 36 V total supply voltage limit. Consider the 200 ns response time for signal processing speeds. Verify that the load requirements do not exceed the 50 mA output current capability.
Part Context
This device belongs to the LM211/LM311 family of single comparators. The LM311 variant is specified for commercial temperature ranges (0 °C to +70 °C), whereas the LM211 covers extended industrial ranges. Both share identical pinouts and core functionality but differ in thermal specifications.
Replacement Considerations
LM211DR2G: Functionally equivalent but rated for -25 °C to +85 °C operating temperature.
