Overview
The LM339ANSRG4 is a quad differential comparator manufactured by Texas Instruments, housed in a 14-pin SOIC package. It operates within a supply voltage range of 2 V to 36 V and supports single or dual power supplies. The device features an open-collector output configuration capable of sinking up to 6 mA per channel. It functions reliably across an operating temperature range of 0°C to +70°C. Key electrical characteristics include a maximum input offset voltage of 5 mV and a typical quiescent current of 500 µA for the entire quad array.
Feature Summary
- Integrates four independent differential comparators into a single compact integrated circuit.
- Features an open-collector output stage compatible with various logic families including TTL and CMOS.
- Designed for low power consumption suitable for battery-operated applications.
Applications
- Temperature monitoring systems
- Voltage level detection circuits
- Over-voltage protection mechanisms
Procurement Notes
Verify the specific suffix 'SRG4' against the manufacturer's official documentation to confirm the tape-and-reel packaging format and lead-free status. Ensure the component meets RoHS compliance requirements for your assembly process. Cross-reference the datasheet revision date to validate the technical specifications provided.
Selection Notes
Select this component when a quad comparator solution is required in a surface-mount SOIC package. Consider the 5 mV input offset voltage specification for precision requirements. Evaluate the 6 mA output sink capability against load requirements. Confirm that the 0°C to +70°C commercial temperature range aligns with the operational environment.
Part Context
This part belongs to the LM339 family of analog comparators from Texas Instruments. It shares functional similarities with other variants like the LM339DRG4 but differs in package type. The family is widely used in industrial and consumer electronics for signal conditioning and threshold detection tasks.
Replacement Considerations
LM339AN/NOPB offers a through-hole PDIP alternative with similar electrical characteristics. LM339DRG4 provides a pin-compatible surface-mount option in an SOIC package. Verify pinout compatibility and thermal performance before substituting.
