Logic Output Optoisolators Procurement Notes

Verify the specific ordering suffix R2 corresponds to the required tape and reel packaging format before procurement. Confirm that the 8-SOIC surface-mount package dimensions align with the target PCB footprint. Ensure the supply chain source is authorized to guarantee component authenticity and adherence to RoHS compliance standards. Cross-reference the manufacturer part number with distributor catalogs to avoid substitution errors during purchasing.

Logic Output Optoisolators Selection Notes

Select this component when a single-channel optocoupler with 25 Mbps data rate capability is required. The 20kV/µs common-mode transient immunity makes it suitable for noisy industrial environments. Consider the 8-SOIC package for surface-mount assembly constraints. Verify that the 3750 Vrms isolation voltage meets system safety requirements. Evaluate thermal management needs based on the 90 mW power dissipation rating at maximum operating temperatures.
