Digital Isolators Procurement Notes

Verify the specific suffix 'B' indicates the correct package variant (8-SMD Gull Wing) and 'C' denotes the temperature grade. Confirm that the manufacturer has scheduled this part for obsolescence, as availability may be limited or discontinued. Ensure the application requirements align with the 15 Mbps data rate and 3750 Vrms isolation rating before finalizing procurement decisions.

Digital Isolators Selection Notes

Select this component when a unidirectional isolator with LED emulator input functionality is required. It is suitable for replacing traditional optocouplers in space-constrained designs due to its SOIC-8 footprint. Consider the 35 kV/µs CMTI rating for noisy environments. Verify that the 1.7 mA supply current meets power budget constraints compared to higher-current alternatives.
