Overview
The LM339NSRG4 is a quad differential comparator manufactured by Texas Instruments, housed in a 14-pin SOIC package. It operates within a temperature range of 0 to 70 degrees Celsius and features open-collector outputs. Key electrical specifications include a maximum average input bias current of 0.05 µA, a maximum input offset voltage of 5000 µV, and a length of 10.3 mm. The device complies with RoHS standards and is lead-free.
Feature Summary
- Integrates four independent differential comparators into a single integrated circuit for compact signal processing designs.
- Features open-collector output configuration allowing flexible interfacing with various logic families and voltage levels.
- Operates reliably across the standard commercial temperature range suitable for general-purpose electronic applications.
Applications
- General-purpose analog-to-digital conversion interfaces
- Voltage monitoring circuits
- Level shifting applications
Procurement Notes
Verify the specific ordering suffix against official manufacturer documentation to ensure correct package type and temperature grade. Confirm RoHS compliance status and lead-free certification requirements match project specifications before procurement. Cross-reference the part number with authorized distributors to validate authenticity and supply chain integrity.
Selection Notes
Select this component when a quad comparator solution is required for commercial temperature environments. Consider the open-collector output structure for compatibility with different logic voltages. Evaluate the input bias current and offset voltage parameters against the precision requirements of the target application circuit design.
Part Context
This device belongs to the LM339 family of quad comparators from Texas Instruments. It shares functional similarities with other members like the LM339DRG4 but differs in packaging and specific thermal characteristics. The series is widely used in industrial and consumer electronics for basic threshold detection tasks.
Replacement Considerations
The LM339DRG4 serves as a direct pin-compatible alternative offering similar quad comparator functionality in an SOIC-14 package. Verify that the replacement meets the same operating temperature and electrical specification requirements for the intended application.
