Si860x Data Sheet
Bidirectional I2C Isolators with Unidirectional Digital Channels
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 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.
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.
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.

Ordering Guide
1. Ordering Guide
Industrial and Automotive Grade OPNs
Industrial-grade devices (part numbers having an “-I” in their suffix) are built using well-controlled, high-quality manufacturing flows to
ensure robustness and reliability. Qualifications are compliant with JEDEC, and defect reduction methodologies are used throughout
definition, design, evaluation, qualification, and mass production steps.
Automotive-grade devices (part numbers having an “-A” in their suffix) are built using automotive-specific flows at all steps in the manu-
facturing process to ensure robustness and low defectivity. These devices are supported with AIAG-compliant Production Part Approval
Process (PPAP) documentation, and feature International Material Data System (IMDS) and China Automotive Material Data System
(CAMDS) listing. Qualifications are compliant with AEC-Q100, and a zero-defect methodology is maintained throughout definition, de-
sign, evaluation, qualification, and mass production steps.

Note:
1. All packages are RoHS-compliant with peak reflow temperature of 260 °C according to the JEDEC industry standard classifica-
tions and peak solder temperature.
2. “Si” and “SI” are used interchangeably.
3. An "R" at the end of the part number denotes tape and reel packaging option.
4. Temperature range is –40 to 125 °C.
5. Automotive-Grade devices (with an "–A" suffix) are identical in construction materials, topside marking, and electrical parameters
to their Industrial-Grade (with an "–I" suffix) version counterparts. Automotive-Grade products are produced utilizing full automo-
tive process flows and additional statistical process controls throughout the manufacturing flow. The Automotive-Grade part num-
ber is included on shipping labels.
6. In the top markings of each device, the Manufacturing Code represented by either “RTTTTT” or “TTTTTT” contains as its first
character a letter in the range N through Z to indicate Automotive-Grade.
