Overview
The LM311PG4 is a high-speed differential comparator manufactured by Texas Instruments, housed in an 8-pin TSSOP package. It operates within a temperature range of 0 to 70 degrees Celsius and supports supply voltages up to 30V. Key electrical specifications include a maximum average input bias current of 0.25 µA and a maximum input offset voltage of 10000 µV. The device features a single comparator function with open-collector outputs and includes strobe inputs for precise signal timing control.
Feature Summary
- High-speed differential comparison capability
- Integrated strobe input for signal gating
- Open-collector output configuration
Applications
- Voltage level detection circuits
- Zero-crossing detectors
- Logic interface adapters
Procurement Notes
Verify the component authenticity by checking the manufacturer marking against official datasheet standards. Confirm the specific suffix 'G4' indicates lead-free and RoHS compliance as documented by Texas Instruments. Ensure the package type matches the required 8-TSSOP footprint for your design.
Selection Notes
Select this component when a single high-speed comparator with strobe functionality is required. Consider the 0 to 70 degrees Celsius operating range for commercial applications. Evaluate the 10000 µV maximum input offset voltage against your circuit's precision requirements before finalizing the design.
Part Context
This part belongs to the LM311 family of differential comparators from Texas Instruments. It shares functional similarities with other variants like the LM311PWRG4 but differs in packaging and specific ordering suffixes. The family is known for providing robust performance in general-purpose comparison tasks.
Replacement Considerations
The LM311DRE4 is a documented substitute offering similar high-speed differential comparison capabilities. Verify pin compatibility and electrical specifications before implementation.
