Overview
The LM3302D is a quad differential analog comparator manufactured by Texas Instruments, housed in a 14-pin SOIC surface-mount package. It operates on a single supply voltage ranging from 2 V to 28 V with a typical quiescent current of 16 mA. The device features a response time of 300 ns and an input offset voltage of 20 mV. It supports both CMOS and TTL output logic levels and functions within an operating temperature range of -40°C to +85°C.
Feature Summary
- Integrates four independent differential comparators into a single compact package for space-constrained designs.
- Provides flexible digital output compatibility with standard CMOS and TTL logic families.
- Operates reliably across a wide single-supply voltage range suitable for various power environments.
Applications
- General-purpose signal threshold detection circuits
- Voltage monitoring systems requiring multiple comparison channels
- Logic interface adapters between analog sensors and digital processors
Procurement Notes
Verify the specific suffix against the manufacturer's official datasheet to confirm pinout and electrical characteristics match the design requirements. Ensure the component source is authorized to guarantee authenticity and traceability. Cross-reference the ordering part number with the latest TI documentation to avoid discrepancies in package type or temperature grade.
Selection Notes
Select this component when a quad comparator configuration is required with low power consumption and broad supply voltage tolerance. It is suitable for applications needing fast response times without the complexity of operational amplifiers. Consider the SOIC-14 package constraints and thermal performance during layout planning.
Part Context
