Procurement Notes

Verify the obsolete status of this component before integration into new designs. Confirm availability through authorized distributors or secondary markets. Ensure that any replacement strategy accounts for the discontinuation timeline. Validate pin compatibility if substituting with similar family members. Check RoHS compliance documentation for regulatory requirements.

Selection Notes

Select this part when a fixed 5.9 V detection threshold is required. Consider the SSOP-3 package size constraints for PCB layout. Evaluate the open-drain output capability against pull-up resistor requirements. Assess the ±1% precision against system tolerance needs. Verify the 10 V maximum supply voltage aligns with the input source.
