Procurement Notes

Verify the specific package marking and date code against the manufacturer's latest datasheet revision to ensure component authenticity. Confirm that the ordering suffix matches the required tape-and-reel quantity specifications. Check for any recent product change notifications regarding material or manufacturing site updates before finalizing procurement orders.

Selection Notes

Select this component when design requirements prioritize ultra-low power consumption alongside high precision in a compact form factor. The open collector output necessitates an external pull-up resistor; ensure the chosen resistor value aligns with the desired switching speed and load capacitance constraints. Verify that the supply voltage remains within the specified 2.7 V to 12 V range for optimal CMRR and PSRR performance.
