LM2901NG4

Overview

The LM2901NG4 is a quad differential comparator manufactured by Texas Instruments, housed in a 14-pin PDIP package. It operates on single or dual power supplies ranging from 2V to 36V. Key electrical parameters include a typical response time of 700ns, an input offset voltage of 7mV, and an input bias current of 250nA. The device supports open collector outputs compatible with CMOS and TTL logic levels.

Feature Summary

• Quad differential architecture for multi-channel signal comparison
• Wide supply voltage range supporting single and split configurations
• Open collector output stage enabling flexible logic interfacing

Applications

• Level detection circuits
• Low-level sensing applications
• Memory circuit designs

Procurement Notes

Verify the specific suffix 'G4' against the manufacturer's official documentation to confirm lead-free compliance and RoHS status. Ensure the ordering part number matches the exact package style required for your PCB footprint. Cross-reference the datasheet revision date to confirm parameter accuracy before finalizing procurement specifications.

Selection Notes

Select this component when multiple independent comparator channels are required within a single integrated circuit. The wide supply voltage range allows operation across various standard voltage rails without additional regulation. Consider the open collector output requirement for pull-up resistor implementation in the target application design.

Part Context

This device belongs to the LM2901 family of analog comparators designed for general-purpose applications. It provides four independent high-gain comparators optimized for low-power operation. The PDIP-14 package facilitates through-hole mounting for prototyping and industrial equipment requiring robust mechanical connections.

Replacement Considerations

LM2901N: Pin-compatible alternative with similar electrical characteristics. LM339: Quad comparator with comparable functionality but different output structure.
