Overview
The LM311NG is a single voltage comparator manufactured by onsemi, housed in an 8-pin PDIP package. It operates from a single supply of 5.0 V to 30 V or split supplies up to ±15 V. Key electrical specifications include a maximum input offset voltage of 7.5 mV at ±15 V and a maximum input bias current of 250 nA at +25 °C. The device features a response time of 200 ns and can switch output voltages up to 50 V with currents reaching 50 mA. The operating ambient temperature range is specified from 0 °C to +70 °C.
Feature Summary
- Capable of driving DTL, RTL, TTL, or MOS logic loads directly
- Output stage supports switching voltages up to 50 V at currents up to 50 mA
- Includes strobe capability for controlling the output state independently of inputs
- Inputs can be isolated from system ground while outputs drive loads referenced to various supply rails
Applications
- Driving relays, lamps, or solenoids
- Zero-crossing detection circuits
- Interface between analog signals and digital logic systems
Procurement Notes
Verify component authenticity through authorized onsemi channels. Confirm the specific ordering suffix matches the required package type and compliance status. Review the manufacturer's discontinuation notices prior to procurement, as availability may be restricted for legacy inventory.
Selection Notes
Select this component when high-speed comparison is required alongside significant load-driving capabilities. Ensure the application utilizes the open-collector output structure correctly with appropriate pull-up resistors. Verify that the supply voltage and temperature constraints align with the operational requirements of the target circuit design.
Part Context
This part belongs to the LM211/LM311 family of single comparators designed for versatility across wide supply ranges. The LM311 variant specifically targets commercial temperature applications, distinguishing it from the military-grade LM211. It serves as a robust interface solution for converting analog thresholds into digital-compatible signals.
