Overview
The LM311N/NOPB is a high-speed, single-channel differential comparator manufactured by Texas Instruments. It operates within a supply voltage range of 5V to 36V and features an open-collector output compatible with MOS, CMOS, TTL, and ECL logic families. The device includes a strobe input for controlling the output state. It is housed in an 8-pin DIP package and supports an operating temperature range from 0°C to 70°C.
Feature Summary
- High-speed differential comparison capability
- Logic-compatible open-collector output
- Strobe input functionality for output control
Applications
- Voltage monitoring systems
- Zero-crossing detection circuits
- Logic interface conversion
Procurement Notes
Verify that the ordering suffix /NOPB confirms lead-free and RoHS compliance as per Texas Instruments specifications. Confirm the package type matches the required through-hole DIP-8 form factor for the specific application board design.
Selection Notes
Select this component when a single-channel comparator with strobe functionality is required. Ensure the application utilizes single or dual power supplies within the specified voltage limits. Verify that the open-collector output configuration aligns with the downstream logic requirements.
Part Context
This part belongs to the LMx11 family of comparators, which are designed for general-purpose high-speed applications. The LM311 variant specifically offers differential inputs and a strobe pin, distinguishing it from simpler comparator models within the same series.
Replacement Considerations
LM311N is the non-RoHS equivalent. LM311DR is the surface-mount SOIC version.
