SI8622HC-B-ISR

Digital Isolators Overview

The SI8622HC-B-ISR is a general-purpose digital isolator from Skyworks Solutions, featuring two unidirectional channels with capacitive coupling. It supports data rates up to 150 Mb/s and provides an isolation voltage of 3750 Vrms. The device operates on a supply voltage range of 2.5 V to 5.5 V, with a typical operating current of 8.2 mA. Key timing parameters include a propagation delay of 8 ns, rise/fall times of 4 ns, and a pulse width distortion of 0.2 ns. It functions within a temperature range of -40°C to +125°C and is housed in an 8-SOIC package.

Digital Isolators Procurement Notes

Verify the specific suffix 'HC' against official Skyworks documentation to confirm compliance requirements. Ensure the 'ISR' designation matches the required tape-and-reel packaging format for automated assembly processes. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability before procurement.

Digital Isolators Selection Notes

Select this component when bidirectional isolation is not required, as it offers only unidirectional channels. Consider the 8-SOIC package dimensions for PCB layout constraints. Evaluate the 150 Mb/s data rate against system throughput needs. Verify that the 3750 Vrms isolation rating meets the safety standards of the target application environment.

Digital Isolators Part Context

This device belongs to the Si86xx family of digital isolators, which utilize Skyworks' proprietary capacitive isolation technology. The family is designed to replace traditional magnetic couplers, offering improved reliability and lower power consumption.
