Overview
The LM311DE4 is a high-speed differential comparator manufactured by Texas Instruments, housed in an 8-SOIC package. It operates within a supply voltage range of 3.5V to 30V (single) or ±1.75V to ±15V (dual). Key electrical characteristics include a maximum input offset voltage of 10mV and a maximum average bias current of 0.25µA at 25°C. The device features a response time of 115ns and supports output configurations including MOS, open-collector, open-emitter, and TTL compatibility.
Feature Summary
- High-speed differential comparison capability with strobe functionality
- Versatile output interface supporting multiple logic families
- Wide single and dual power supply operation range
Applications
- Zero-crossing detection circuits
- Voltage monitoring systems
- Logic level conversion interfaces
Procurement Notes
Verify the component authenticity against official Texas Instruments documentation. Confirm that the ordering suffix 'E4' indicates lead-free status and RoHS compliance as specified in the manufacturer's datasheet. Ensure the package type matches the required 8-SOIC footprint for your design implementation.
Selection Notes
Select this component when high-speed differential comparison is required alongside flexible output drive options. Consider the 115ns response time and low bias current for precision applications. Verify that the operating temperature range of 0°C to 70°C aligns with your environmental requirements.
Part Context
This part belongs to the LM111/LM211/LM311 family of comparators, differentiated primarily by temperature ranges and manufacturing processes. The 'D' suffix denotes the SOIC package, while 'E4' signifies lead-free construction compliant with specific environmental standards defined by the manufacturer.
Replacement Considerations
LM311DR: Same functional comparator in SOIC-8 package but without the E4 lead-free designation.
