LM339ADRE4

Overview

The LM339ADRE4 is a quad differential analog comparator manufactured by Texas Instruments, housed in a 14-pin SOIC surface-mount package. It operates within a supply voltage range of 2 V to 30 V and draws a typical quiescent current of 500 uA. The device features an open collector output capable of sinking up to 6 mA per channel. Key electrical specifications include a maximum input offset voltage of 3 mV, an input bias current of 250 nA, and a response time of 1.3 us. It supports CMOS and TTL logic compatibility and functions within a commercial temperature range of 0°C to +70°C.

Feature Summary

• Integrates four independent differential comparators in a single compact package for space-constrained designs.
• Features open-collector outputs that allow flexible interfacing with various digital logic families including CMOS and TTL.
• Operates on a wide single-supply voltage range from 2 V to 30 V, suitable for diverse power environments.

Applications

• General-purpose voltage monitoring circuits
• Threshold detection systems
• Logic level shifting interfaces

Procurement Notes

Verify the specific suffix 'E4' indicates lead-free compliance and RoHS status as documented by the manufacturer. Confirm the SOIC-14 package dimensions match your PCB footprint requirements. Check the datasheet for the latest lifecycle status, as availability may vary by region. Ensure the operating temperature range meets your application's environmental conditions.

Selection Notes

Select this component when multiple independent comparison channels are required in a low-power, single-supply application. Consider the 1.3 us response time for speed requirements. Verify that the open-collector output architecture aligns with your pull-up resistor strategy. Compare against the LM339ADR if tape-and-reel packaging variations are needed.

Part Context

This part belongs to the LM339 family of quad comparators, widely used for general-purpose signal processing. It serves as a standard solution for applications requiring multiple voltage comparisons without the complexity of operational amplifiers. The RE4 suffix typically denotes specific packaging and environmental compliance attributes defined by Texas Instruments.

Replacement Considerations

Direct pin-compatible alternatives include the LM339ADR and LM339PWRE4. Verify that substitute parts maintain the same 3 mV max input offset voltage and 500 uA quiescent current specifications to ensure circuit performance parity.
