Supervisors Procurement Notes

Verify the specific suffix ART-RL against official Analog Devices documentation to confirm reel packaging and tape specifications. Ensure the threshold voltage code D3 corresponds to the required 3.08 V trip point for your design. Cross-reference the package marking with the datasheet to distinguish between genuine components and potential counterfeits. Confirm RoHS compliance status through the manufacturer's latest certification records.

Supervisors Selection Notes

Select this component when a fixed 3.08 V threshold is required for single-supply monitoring. The open-drain output allows for flexible interfacing with various logic families. Consider the 200 ms reset delay duration to ensure compatibility with target processor startup times. Verify that the SOT-143 footprint aligns with existing PCB layout constraints and thermal requirements.
