Bidirectional I C Isolators with Unidirectional Digital Channels
KEY FEATURES
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.
• Independent, bidirectional SDA and SCL
isolation channels
• Open drain outputs with 35 mA sink

Supports I C clocks up to 1.7 MHz
All devices in this family include hot-swap, bidirectional SDA and/or SCL isolation chan-
nels 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 ver-
sions (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.
• Unidirectional isolation channels support
additional system signals (Si8605, Si8606)
• Up to 5000 VRMS isolation
• UL, CSA, VDE, CQC recognition
• 60-year life at rated working voltage
• High electromagnetic immunity
• Wide operating supply voltage
• 3.0 to 5.5 V
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.
• Wide temperature range
• –40 to +125 °C
Automotive Grade is available for certain part numbers. These products are built using
automotive-specific flows at all steps in the manufacturing process to ensure the robust-
ness and low defectivity required for automotive applications.
