Overview
The LM339F-E2 is a quad analog comparator manufactured by ROHM Semiconductor, housed in a 14-pin SOP package. It operates within a supply voltage range of 3 V to 32 V and supports ground-sensed inputs and outputs with open collector configuration. Key electrical parameters include a typical response time of 1 µs, a maximum input offset voltage of 4.5 mV, and an operating temperature range from -40°C to +85°C. The device draws a typical quiescent current of 1.2 mA per channel and provides an output current capability of 16 mA.
Feature Summary
- Features ground-sensed input and output capabilities for flexible signal interfacing.
- Utilizes open collector output structure for easy wired-OR connection compatibility.
- Designed for wide operating supply voltage ranges suitable for various power systems.
Applications
- General purpose voltage level detection circuits
- Over-voltage and under-voltage protection monitoring
- Temperature sensing interface circuits
Procurement Notes
Verify the lifecycle status as NRND (Not Recommended for New Designs) before integration into new products. Confirm RoHS compliance details via official documentation. Ensure the SOP-14 package dimensions match the target PCB footprint. Validate that the 3 V to 32 V supply range aligns with system requirements.
Selection Notes
Select this component for applications requiring quad comparators with ground-referenced input/output functionality. Consider the 1 µs response time and 4.5 mV max offset voltage for precision requirements. Verify that the open collector output suits the downstream logic levels. Check thermal dissipation limits against the expected load conditions.
Part Context
This part belongs to the LM339 series of analog comparators. It shares functional similarities with other industry-standard quad comparators but is specific to ROHM's manufacturing specifications. The 'E2' suffix typically denotes environmental compliance or specific packaging variations within the manufacturer's lineup.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided data. Cross-reference with generic LM339 equivalents only if pinout and electrical characteristics are verified against official datasheets.
