Overview
The LM2901N is a quad differential voltage comparator from Texas Instruments, housed in a 14-pin PDIP package. It operates on single supplies from 2 V to 36 V or dual supplies of ±1 V to ±18 V. The device features an open-collector output and supports wired-AND configurations. Key electrical parameters include a typical response time of 1.3 µs, input bias current of 25 nA, and supply current of 0.8 mA. It functions within a temperature range of -40°C to +125°C.
Feature Summary
- Quad independent voltage comparators designed for wide single or dual power supply operation
- Open-collector outputs allow flexible logic interfacing and wired-AND functionality
- Input common-mode voltage range includes ground potential
- Low supply current drain that remains independent of the supply voltage
Applications
- Industrial control systems
- Automotive HEV/EV power trains
- Power supervision circuits
- Oscillators and peak detectors
- Logic voltage translation
Procurement Notes
Verify the specific suffix 'SL' against official documentation to confirm if it denotes a distinct qualification level or variant. Confirm the package type matches the required mounting style. Ensure the operating temperature range aligns with system requirements. Validate RoHS compliance status through the manufacturer's ordering information.
Selection Notes
Select this component when four independent comparators are needed in a single package. It is suitable for applications requiring ground-referenced inputs and high-voltage tolerance. Consider the open-collector output requirement for pull-up resistor implementation. Evaluate thermal performance based on the specific PCB layout and ambient conditions.
Part Context
The LM2901 belongs to the LMx39 family of quad differential comparators. It shares architectural similarities with the LM139, LM239, and LM339 but is characterized for extended industrial temperature ranges. This series is widely used for general-purpose voltage comparison tasks across various electronic designs.

FAQ
Can the LM2901N operate with a single-ended input?
Yes, the device can compare a single signal against a reference voltage by connecting one input to the signal and the other to a fixed reference.
What is the maximum differential input voltage?
The differential input voltage range is equal to the maximum-rated supply voltage, specified as ±36 V.
