The Si860x series of isolators are single-package galvanic isolation solutions for I2C and SMBus serial port applications. These products are based on Skyworks proprietary RF isolation technology and offer shorter propagation delays, lower power consumption, smaller installed size, and more stable operation with temperature and age versus opto couplers or other digital isolators.
All devices in this family include hot-swap, bidirectional SDA and/or SCL isolation channels with open-drain, 35 mA sink capability that operate to a maximum frequency of 1.7 MHz. The 8-pin version (Si8600) supports bidirectional SDA and SCL isolation; the Si8602 supports bidirectional SDA and unidirectional SCL isolation, and the 16-pin versions (Si8605, Si8606) feature two unidirectional isolation channels to support additional system signals, such as interrupts or resets.
All versions contain protection circuits to guard against data errors when an unpowered device is inserted into a powered system.
