LM339FVJ-E2

Overview

The LM339FVJ-E2 is a quad analog comparator from ROHM Semiconductor, designed for general-purpose applications. It operates within a supply voltage range of 3 V to 32 V and draws a typical operating current of 1.2 mA. The device features four independent channels with open collector outputs capable of sourcing 16 mA each. Key electrical parameters include a maximum input offset voltage of 4.5 mV, an input bias current of 250 nA, and a response time of 1 µs. It supports ground-sense inputs and outputs, functioning reliably across an extended temperature range from -40 °C to +85 °C in a TSSOP-B-14 package.

Feature Summary

• Supports ground-sensed input and output signals for flexible circuit integration
• Features open collector outputs compatible with various logic families
• Provides wide operating supply voltage capability for diverse power environments

Applications

• General purpose voltage monitoring circuits
• Threshold detection systems
• Level shifting interfaces

Procurement Notes

Verify the component status before procurement as it is marked NRND (Not Recommended for New Designs). Confirm that the TSSOP-B-14 package dimensions match the target PCB footprint. Ensure the open collector output configuration aligns with the downstream logic requirements. Check RoHS compliance documentation if environmental regulations apply to the final assembly.

Selection Notes

Select this component when a quad comparator with ground-sense capability is required. The low input offset voltage ensures accurate threshold detection. The wide supply voltage range accommodates single-supply designs. Consider the thermal dissipation limits of the TSSOP-B-14 package under high ambient temperatures or heavy load conditions.

Part Context

This part belongs to the LM339 series of analog comparators manufactured by ROHM Semiconductor. It shares functional similarities with other quad comparators but is distinguished by its specific pinout and package type. The E2 suffix typically indicates lead-free and halogen-free compliance. It serves as a direct replacement for legacy LM339 variants in existing designs requiring surface-mount technology.

Replacement Considerations

Check for pin-compatible alternatives such as LM339FV-E2 or LM339DR from other manufacturers if supply constraints exist. Verify that substitute parts maintain the same open collector output structure and ground-sense input specifications.
