Procurement Notes

Verify the specific suffix G3 against the manufacturer's current product status documentation, as lead times and availability may vary. Confirm RoHS compliance details directly with the supplier or official datasheet before procurement. Ensure the TSSOP-14 package dimensions match the target PCB footprint design constraints. Cross-reference the ordering part number with the latest Texas Instruments release notes to confirm active manufacturing status.

Selection Notes

Select this component when multiple independent comparator functions are required in a space-constrained design. The wide supply voltage range makes it suitable for systems without regulated mid-rail supplies. Consider the open-collector output requirement for pull-up resistor implementation. Evaluate the 1.3 µs response time against the signal frequency requirements of the application to ensure adequate propagation delay performance.

Part Context

The LM2901 series belongs to Texas Instruments' family of low-power analog comparators. This specific variant integrates four comparators into a single integrated circuit. The PWR designation indicates the TSSOP-14 surface-mount package type. The G3 suffix typically denotes environmental compliance attributes defined by the manufacturer. This component serves as a general-purpose solution for voltage monitoring and signal conditioning tasks.

Replacement Considerations

The LM2901PWRG4 is a documented equivalent variant within the same product family. Verify pin compatibility and electrical specifications before substitution. Check for any changes in packaging or environmental certifications associated with the suffix change.
