- Optical isolation between input and output stages
Applications
- Computer terminal interfaces
- Industrial system controllers
- Signal transmission between systems of different potentials
Procurement Notes
Verify the specific suffix configuration against the manufacturer datasheet to ensure the correct package type and tape-and-reel availability. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer prior to ordering.
Selection Notes
Select this component when surface-mount technology is required for optocouplers. Ensure the circuit design accommodates the photodarlington output characteristics and verify that the isolation voltage requirements are met by the specific package variant.
Part Context
This part belongs to the ISP8xx series of high-density mounting photodarlington optically coupled isolators. The series offers options for through-hole and surface-mount packages, providing flexibility for various PCB layout constraints while maintaining consistent optical coupling performance.
Replacement Considerations
Check for direct pin-compatible replacements within the same family, such as ISP815 or ISP845 variants, ensuring identical package dimensions and electrical specifications before substitution.
