Description

The Si860x series of isolators are single-package galvanic isolation solutions for I 2 C

and SMBus serial port applications. These products are based on Silicon Labs

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.

Small size, low installed cost, low power consumption, and short propagation delays

make the Si860x family the optimum solution for isolating I 2 C and SMBus serial

ports.
