Digital Isolators Procurement Notes

Verify the specific suffix 'IS2' against official Skyworks documentation to confirm pinout and packaging details. Ensure compatibility with required isolation standards such as UL or IEC before integration. Confirm that the 16-SOIC narrow body dimensions match the target PCB footprint constraints.

Digital Isolators Selection Notes

Select this component when high-speed unidirectional isolation is required alongside robust transient immunity. The 150 Mbps rate suits applications needing faster communication than standard isolators. Consider the 5000 Vrms rating for safety-critical boundaries. Evaluate power consumption against system thermal limits given the 6.6 mA per channel draw.

Digital Isolators Part Context
