SI8655BA-B-IU

Digital Isolators Overview

The SI8655BA-B-IU is a five-channel digital isolator from Skyworks Solutions, utilizing capacitive coupling technology for signal transmission. It operates within a supply voltage range of 2.375 V to 5.5 V and supports data rates up to 150 Mb/s. The device provides an isolation voltage of 1000 Vrms with a common-mode transient immunity of 35 kV/µs. Key timing parameters include a propagation delay of 8 ns, rise and fall times of 4 ns, and a pulse width distortion of 4.5 ns. It is qualified under AEC-Q100 standards and functions reliably across an extended temperature range from -40°C to +125°C.

Digital Isolators Feature Summary

Digital Isolators Procurement Notes

Verify the specific suffix 'IU' to confirm the QSOP-16 tube package configuration. Ensure that the 1000 Vrms insulation rating aligns with the system's safety isolation requirements. Confirm AEC-Q100 compliance if the application mandates automotive-grade certification. Cross-reference the operating temperature range against environmental conditions.

Digital Isolators Selection Notes

Select this component when five isolated channels are required for unidirectional signal paths. The 150 Mb/s data rate suits general-purpose communication interfaces. Consider the 1000 Vrms isolation level as sufficient for many industrial applications. Evaluate the 8 ns propagation delay for timing-sensitive circuit designs.

Digital Isolators Part Context

This part belongs to the Si865x family of digital isolators. It shares architectural similarities with other members like the SI8655BD-B-ISR but differs in insulation voltage and packaging. The family utilizes advanced CMOS processes to achieve high performance in a compact form factor.

Digital Isolators Replacement Considerations

SI8655BA-B-IS1R offers identical electrical specifications but uses an SOIC-Narrow-16 reel package instead of the QSOP-16 tube.
