Procurement Notes
Verify the specific suffix 'GR' indicates tape and reel packaging containing 3000 pieces per reel as documented by the manufacturer. Confirm that the 16-pin SOP footprint matches your board layout requirements. Ensure compatibility with the specified 3750 Vrms isolation rating for your safety standards. Cross-reference the datasheet to confirm pinout alignment before integration into production designs.
Selection Notes
Select this component when multiple independent isolation channels are required within a single package footprint. The photovoltaic output type is suitable for applications demanding low input drive currents. Consider the 16-pin SOP form factor for space-constrained designs where quad-channel isolation is necessary without increasing board area significantly compared to discrete solutions.
Part Context
Isocom Components specializes in infrared optoelectronic devices, including optocouplers and photo-switches. The IS280 series represents their standard line of high-reliability isolation components.
