Overview
The LM339FV-E2 is a quad analog comparator manufactured by ROHM Semiconductor, housed in an SSOP-14 surface-mount package. It operates within a supply voltage range of 3 V to 32 V and supports ground-sensed inputs and outputs. Key electrical parameters include a typical response time of 1 µs, a maximum input offset voltage of 4.5 mV, and a typical quiescent current of 1.2 mA. The device features open-collector outputs capable of sourcing up to 16 mA per channel. It is rated for operation between -40°C and +85°C with a power dissipation of 870 mW.
Feature Summary
- Quad configuration with ground-sense capability for both input and output signals
- Open-collector output structure allowing flexible interfacing with various logic families
- Wide operating supply voltage range supporting single or dual power sources
- Low input offset voltage ensuring accurate signal comparison
Applications
- General purpose voltage monitoring circuits
- Threshold detection systems
- Over-voltage protection schemes
Procurement Notes
Verify the component status as Not Recommended for New Designs (NRND) before integration into new products. Confirm that the SSOP-14 package dimensions align with existing PCB footprints. Ensure supply chain availability accounts for potential end-of-life constraints associated with this lifecycle stage.
Selection Notes
Select this component when a quad comparator with ground-referenced input/output ranges is required. The open-collector output necessitates external pull-up resistors for proper logic level generation. Consider the 1 µs response time and 4.5 mV offset voltage limits against specific application accuracy and speed requirements.
Part Context
This part belongs to the LM339 series of analog comparators. It shares functional similarities with other quad comparators but is distinguished by its specific pinout, package type, and manufacturer-specific electrical characteristics. It serves as a direct replacement for legacy LM339 variants where the SSOP-14 form factor is mandated.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with alternative quad comparators based on pin-to-pin mapping and electrical parameter equivalence.
