Overview
The LM311H/NOPB is a high-speed voltage comparator manufactured by Texas Instruments, belonging to the LM111-N/LM211-N/LM311-N series. It features an open-collector output and operates within a supply voltage range of 5 V to 36 V. The device exhibits a typical response time of 200 ns and draws a maximum operating supply current of 6 mA. It supports a differential input type with an input bias current of 100 nA and an input offset current of 10 nA. The component provides a channel output current capability of 50 mA per channel and has a power dissipation rating of 500 mW. It is housed in an 8-pin TO-99 package and functions reliably across a temperature range from -55°C to +125°C.
Feature Summary
- Features an open-collector output configuration compatible with DTL, MOS, RTL, and TTL logic families.
- Provides high-speed performance with a typical response time of 200 ns for rapid signal comparison.
- Supports wide single or dual power supply operation ranging from 5 V to 36 V.
- Capable of sourcing up to 50 mA of output current per channel for direct drive applications.
Applications
- Voltage monitoring systems requiring fast threshold detection
- Logic level translation between different digital families
- Peak hold circuits for signal processing
Procurement Notes
Verify the specific suffix 'H' indicates the military-grade variant within the LM111/211/311 series. Confirm the 'NOPB' designation ensures lead-free packaging compliance. Check the datasheet for exact pinout configurations associated with the TO-99-8 package. Ensure environmental specifications match project requirements for the extended temperature range.
Selection Notes
Select this component when high speed and wide supply voltage ranges are required. The open-collector output allows flexible interfacing with various logic levels. Consider the TO-99 package for through-hole mounting needs. Evaluate the 50 mA output current capability against load requirements. Verify thermal management strategies for the specified power dissipation limits.
Part Context
The LM311H/NOPB is part of the LM111-N/LM211-N/LM311-N family of voltage comparators. This series is designed for general-purpose analog comparison tasks. The 'H' suffix typically denotes enhanced performance or specific grade variants within the manufacturer's lineup. The device serves as a standard solution for applications needing fast response times and robust output driving capabilities.
Replacement Considerations
Compatible substitutes include LM111H/NOPB and LM211H/NOPB from the same manufacturer series. These parts share similar electrical characteristics and pinouts. Verify functional equivalence before substitution. Ensure package compatibility remains consistent during replacement.
