Overview
The LM339DTBR2 is a quad analog comparator manufactured by onsemi, housed in a TSSOP-14 surface-mount package. It operates with a single supply voltage ranging from 3.0 V to 36 V or split supplies of ±1.5 V to ±18 V. The device features an open-collector output capable of sinking up to 16 mA and is compatible with TTL and CMOS logic families. Electrical characteristics include a typical input bias current of 25 nA, an input offset voltage of ±5.0 mV, and a response time of 1.3 µs. It functions within an ambient temperature range of 0°C to +70°C.
Feature Summary
- Supports single and split power supply configurations for flexible system integration.
- Features low input bias current and wide common mode voltage range extending to ground.
- Provides open-collector outputs compatible with various digital logic standards.
Applications
- Level detection circuits
- Low-level sensing applications
- Memory interface designs
Procurement Notes
Verify the specific suffix DTBR2 confirms the TSSOP-14 package and commercial temperature grade (0°C to +70°C). Ensure the ordering part number matches the required lead-free and RoHS compliance specifications. Confirm that the manufacturer source aligns with onsemi documentation for accurate electrical parameter validation.
Selection Notes
Select this component when a quad comparator with open-collector outputs is required for interfacing with standard logic families. Consider the TSSOP-14 package for space-constrained surface-mount designs. Evaluate the 1.3 µs response time against application speed requirements and ensure the operating voltage stays within the specified 36 V maximum limit.
Part Context
This device belongs to the LM339 family of single-supply quad comparators designed for consumer, automotive, and industrial electronics. It shares architectural similarities with the LM239 and LM2901 series but is optimized for commercial temperature ranges. The TSSOP-14 variant offers a compact footprint compared to traditional DIP packages while maintaining identical pinout functionality.

FAQ
What is the input common mode voltage range?
The input common mode voltage range extends from ground (0 V) to the positive supply voltage minus 1.5 V.
Is the output push-pull or open-collector?
The LM339DTBR2 utilizes an open-collector output structure, requiring an external pull-up resistor for proper operation.
