• General-purpose isolated communication interfaces

Digital Isolators Procurement Notes

Verify the specific suffix 'B-ISR' against official Skyworks documentation to confirm the tape-and-reel packaging format and lead-free status. Ensure the procurement channel provides valid traceability for automotive or industrial grade requirements if applicable. Cross-reference the datasheet revision date to confirm current manufacturing status and compliance certifications before finalizing orders.

Digital Isolators Selection Notes

Select this component when a single-channel unidirectional isolator is required with high CMTI performance. The 15 Mbps data rate suits moderate-speed digital signals. Consider the SOIC-8 footprint for PCB layout compatibility. Verify that the 3750 Vrms isolation rating meets the system's safety standards. The LED input type simplifies interface design compared to standard logic inputs.

Digital Isolators Part Context

This part belongs to the Si8711 family of digital isolators from Skyworks Solutions. The family utilizes silicon dioxide (SiO2) insulation technology for high reliability. The SI8711AC variant specifically targets general-purpose applications requiring cost-effective isolation solutions. The B-ISR suffix denotes the specific package and reel configuration for surface-mount assembly.

Digital Isolators Replacement Considerations

Official parametric equivalents include the SI8710AC-B-ISR. When substituting, verify pinout compatibility and ensure the alternative part meets the same 3750 Vrms isolation and 15 Mbps speed requirements. Check for any differences in propagation delay or power consumption that might impact system timing.
