Digital Isolators Procurement Notes

This component is scheduled for obsolescence and will be discontinued by the manufacturer. Availability is limited, and distributors may not stock this item in all regions. Verify end-of-life status and final purchase dates directly with authorized suppliers before design commitment. Ensure alternative sourcing strategies are in place due to impending discontinuation.

Digital Isolators Selection Notes

Select this part for applications requiring a single unidirectional channel with automotive qualification. Consider the 15 Mb/s data rate and 50 ns delay for timing-critical signals. The DIP-8 package suits through-hole designs. Evaluate the 3750 Vrms isolation barrier against system safety requirements. Confirm compatibility with 2.5 V to 5.5 V logic levels and check if the unidirectional nature meets the specific signal flow needs of the circuit.

Digital Isolators Part Context
