Description
The Si860x series of isolators are single-package galvanic isolation solutions for I²C
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 I²C and SMBus serial
ports.
