Overview
The LM311MX is a high-speed differential comparator manufactured by Texas Instruments, housed in an 8-pin SOIC surface-mount package. It operates with a supply voltage range of 3.5V to 30V and features an open-collector output compatible with CMOS and TTL logic families. The device provides a typical response time of 115ns and includes strobe functionality for precise signal gating. Designed for industrial applications, it functions within a temperature range of 0°C to +70°C, drawing a typical operating current of 7.5mA.
Feature Summary
- High-speed differential comparison capability
- Integrated strobe input for signal control
- Open-collector output supporting multiple logic families
Applications
- Voltage level detection circuits
- Fast analog-to-digital conversion interfaces
- Over-voltage protection systems
Procurement Notes
Verify the specific suffix 'MX' against official Texas Instruments documentation to confirm the exact package variant and tape-and-reel specifications. Ensure compatibility with existing PCB footprints for the 8-SOIC form factor. Cross-reference the datasheet revision date to validate electrical parameters against current production standards before finalizing procurement orders.
Selection Notes
Select this component when a single-channel comparator with strobe functionality is required for high-speed switching applications. Consider the open-collector output architecture for interfacing with various logic levels. Evaluate the 115ns response time against system timing requirements to ensure adequate performance margins for the intended signal processing speeds.
Part Context
The LM311MX belongs to the LM311 family of high-speed comparators from Texas Instruments. This series is widely recognized for its versatility in general-purpose analog signal processing. The MX suffix typically denotes a specific tape-and-reel packaging option within the standard SOIC-8 footprint, facilitating automated assembly processes in manufacturing environments.
Replacement Considerations
LM311DR: Standard SOIC-8 version with similar electrical characteristics. LM311N: DIP-8 through-hole alternative for prototyping or legacy board upgrades.
