Overview
The LM311DG is a single voltage comparator manufactured by onsemi in an SOIC-8 package. It operates from a single supply of 5.0 V to 30 V or split supplies up to ±15 V. Key electrical parameters include a maximum input bias current of 250 nA, a response time of 200 ns, and an output current capability of 50 mA. The device supports differential input voltages up to ±30 V and functions within an operating temperature range of 0 °C to +70 °C.
Feature Summary
- Capable of driving DTL, RTL, TTL, or MOS logic loads
- Output can switch voltages up to 50 V at currents up to 50 mA
- Includes strobe capability for controlling output state
- Pins 5 and 6 allow for offset balance adjustment
Applications
- Driving relays, lamps, or solenoids
- Zero-crossing detector circuits
- Comparators interfacing with CMOS logic
Procurement Notes
Verify the specific suffix 'DG' corresponds to the SOIC-8 package and Pb-Free status as defined in the official ordering information. Confirm that the component meets RoHS compliance requirements for your intended assembly process. Check the manufacturer's discontinuation notices, as certain variants within this family may be marked as not recommended for new designs.
Selection Notes
Select this component when a versatile comparator capable of handling high-voltage switching is required. It is suitable for applications needing isolation between inputs and system ground while driving loads referenced to various supply rails. Ensure the design accounts for the specified response time and power dissipation limits under expected load conditions.
Part Context
This part belongs to the LM211/LM311 series of single comparators. The 'D' suffix indicates the SOIC-8 surface-mount package, while 'G' denotes a Pb-Free manufacturing process. It shares functional characteristics with the LM211 but differs in operating temperature specifications, covering the commercial range.
Replacement Considerations
LM211DG is a compatible alternative within the same family, differing primarily in temperature rating.
