What are the key features of LM3302DRE4?

  • Quad comparator with 4 independent channels in a single 14-pin SOIC package, reducing board area and component count versus discrete single-channel comparators
  • Open-collector/open-drain outputs enabling wired-OR bus configurations and direct interfacing with pull-up resistors to any logic supply voltage
  • Single-supply operation with 20 mV maximum input offset voltage supporting multi-threshold voltage window detection in automotive and industrial control applications

What is LM3302DRE4 used for?

The LM3302DRE4 is ideal for multi-level voltage monitoring, window comparator arrays, and battery cell balancing circuits where 4 independent comparison channels are needed within a compact 14-pin SOIC footprint. Its open-collector outputs allow each channel to independently drive an LED, relay driver, or logic gate pull-up, making it a versatile solution for alarm systems, over/undervoltage protection circuits, and analog-to-digital conversion front ends.

Frequently Asked Questions

How many independent comparator channels does the LM3302DRE4 provide in a single package?

The LM3302DRE4 contains 4 independent differential comparator channels in one 14-pin SOIC package, allowing a designer to replace 4 discrete single-channel comparators with a single IC, saving PCB space and simplifying the BOM.

What output type does the LM3302DRE4 use, and how should each output be connected to a 3.3V logic rail?

The LM3302DRE4 has open-collector/open-drain outputs, each requiring an external pull-up resistor; connecting a 10 kΩ resistor from each output to the 3.3V rail makes them directly compatible with 3.3V CMOS logic inputs and allows multiple outputs to be wired-ORed together.

What is the maximum input offset voltage of the LM3302DRE4, and which threshold detection accuracy can it guarantee?

The maximum input offset voltage is 20,000 µV (20 mV), meaning the LM3302DRE4 can reliably trip at voltage differences above 20 mV; for tighter thresholds in precision battery monitoring or analog window detection, a lower-offset comparator would be more appropriate.

Is the LM3302DRE4 a functional equivalent to the popular LM339 quad comparator, and what does the 'DRE4' suffix indicate?

The LM3302DRE4 is functionally similar to the LM339 family (quad comparator, open-collector outputs, single or dual supply), with the 'DR' suffix indicating a small-outline 14-pin SOIC package and 'E4' indicating RoHS-compliant lead-free finish with tape-and-reel packaging for automated assembly.
