Supervisors Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm pinout and electrical characteristics. Ensure the procurement source provides valid RoHS compliance data. Confirm availability status as distribution channels may vary. Validate that the 16-pin TSSOP package matches the design requirements. Check for any specific handling instructions related to electrostatic discharge sensitivity.

Supervisors Selection Notes

Select this component when a single-channel supervisor with integrated clock generation is required. It is suitable for applications demanding active-high outputs and programmable timing features. Consider the 5.5V maximum supply limit and 70ms reset delay during circuit design. Evaluate the TSSOP-16 footprint constraints against available board space. Compare performance against standard supervisors if clock integration is not essential.
