Overview
The LM339NSR is a quad analog comparator manufactured by Texas Instruments, housed in a 14-pin DIP package. It features four independent voltage comparators designed for general-purpose applications. The device operates with a single power supply ranging from 2V to 36V or dual supplies of ±1V to ±18V. Key electrical characteristics include an input offset voltage of 2mV and an output sink current capability of up to 16mA. The component supports rail-to-rail common-mode input voltage range and includes internal compensation for stability.
Feature Summary
- Quad configuration providing four independent high-gain comparators within a single integrated circuit
- Wide differential input voltage range compatible with various logic families without additional components
- Open-collector outputs allow flexible interfacing with diverse digital systems and pull-up voltage selection
Applications
- Temperature monitoring and control circuits
- Voltage level detection and sensing applications
- Waveform generation and pulse width modulation
Procurement Notes
Verify the specific suffix 'SR' indicates tape and reel packaging when sourcing. Confirm the manufacturer designation matches Texas Instruments specifications. Ensure the component meets required operating temperature ranges for the intended environment. Cross-reference datasheet revisions to confirm pinout compatibility with existing designs.
Selection Notes
Select this component when multiple independent comparison functions are required in a compact through-hole format. Consider the open-drain output structure for interface flexibility with different logic voltage levels. Evaluate the wide supply voltage range suitability for battery-powered or variable source applications.
Part Context
This part belongs to the LM339 family of quad comparators, widely used in industrial and consumer electronics. The NSR variant specifically denotes the surface-mount or reel-packaged version of the standard DIP-14 LM339N, facilitating automated assembly processes while maintaining identical electrical performance characteristics.
Replacement Considerations
Compatible substitutes include LM339DR and LM339DT from Texas Instruments, which offer equivalent electrical specifications in SOIC and TSSOP packages respectively. Verify pinout compatibility before substitution.
