Logic Output Optoisolators Procurement Notes

Verify the specific suffix '000E' to confirm lead-free compliance and RoHS status, as variants may differ. Ensure the procurement order specifies the PDIP-8 through-hole package type. Confirm that the required operating temperature range aligns with the -40°C to +85°C specification. Check for any specific handling requirements related to the sensitive internal LED structure during assembly.

Logic Output Optoisolators Selection Notes

Select this component when dual-channel isolation with high-speed performance is required. The totem pole output provides stronger drive capability compared to open-collector alternatives. Consider the 3750 Vrms isolation rating for safety-critical applications. Evaluate the 5 Mb/s data rate against system timing requirements. The 8-pin DIP package facilitates easy prototyping and through-hole mounting.
