LM2901NS

Overview

The LM2901NS is a quad differential voltage comparator manufactured by Texas Instruments, housed in a 14-pin SOIC surface-mount package. It features open-collector outputs and supports single supply voltages from 2 V to 36 V or split supplies. Key electrical parameters include a typical response time of 1.3 µs, an input offset voltage of 7 mV, and an operating temperature range of -40 °C to +125 °C.

Feature Summary

• Quad differential architecture for multi-channel signal comparison
• Open-collector output configuration compatible with CMOS and TTL logic levels
• Wide single-supply operational voltage range up to 36 V

Applications

• Level detection circuits
• Low-level sensing applications
• Memory interface monitoring

Procurement Notes

Verify the specific suffix 'NS' against the manufacturer's official datasheet to confirm pinout compatibility and package dimensions. Ensure the component meets required RoHS compliance standards for the target assembly process. Cross-reference the ordering part number with authorized distributors to validate authenticity and traceability before procurement.

Selection Notes

Select this component when multiple independent voltage comparisons are required within a compact surface-mount footprint. The wide supply voltage range allows operation in diverse power environments without level shifting. Verify that the open-collector output requirement aligns with the downstream logic interface pull-up resistor specifications.

Part Context

This device belongs to the LMx39/LM2901 family of quad comparators designed for general-purpose analog signal processing. It shares functional similarities with the LM239 but offers specific performance characteristics tailored for industrial and consumer electronics. The SOIC-14 package facilitates automated PCB assembly processes.

Replacement Considerations

LM2901N (PDIP variant), LM2901NSR (Tape & Reel variant). Verify package type and reel specifications when substituting.
