LM2901DG4

Overview

The LM2901DG4 is a quad differential comparator manufactured by Texas Instruments, housed in a 14-pin SOIC surface-mount package. It operates on single or dual power supplies ranging from 2 V to 32 V. The device features an open-collector output type and delivers a typical response time of 1.3 µs. It supports input bias currents up to 250 nA and maintains an operating temperature range from -40 °C to +125 °C.

Feature Summary

• Quad differential architecture for multi-channel signal comparison
• Open-collector outputs compatible with CMOS, TTL, DTL, and ECL logic families
• Wide supply voltage operation supporting both single and split configurations

Applications

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

Procurement Notes

Verify the specific suffix 'DG4' against the manufacturer's current datasheet to confirm lead-free status and RoHS compliance. Ensure the SOIC-14 package dimensions match the target PCB footprint. Confirm that the open-collector output requirements align with the system pull-up resistor configuration before finalizing procurement.

Selection Notes

Select this component when multiple independent differential comparisons are required within a single integrated circuit. The wide supply voltage range allows flexibility in power design. Consider the 1.3 µs response time for timing-critical paths. Verify that the industrial temperature range meets environmental requirements for the intended deployment scenario.

Part Context

This part belongs to the LM2901 family of analog comparators designed for general-purpose applications. It provides four independent comparators in a compact surface-mount form factor. The device is engineered for reliability in consumer, automotive, and industrial electronic environments requiring robust signal processing capabilities.

Replacement Considerations

LM2901DR serves as a direct pin-compatible alternative within the same product family.
