Description
The Si840x 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 SCL
isolation channels with open-drain, 35 mA sink capability and operate to a
maximum frequency of 1.7 MHz. The 8-pin version (Si8400/01) supports
bidirectional SDA and SCL isolation; the Si8402 supports bidirectional SDA
and unidirectional SCL isolation, and the 16-pin version (Si8405) features
two unidirectional isolation channels to support additional system signals,
such as an interrupt or reset. All versions contain protection circuits to
guard against data errors if an unpowered device is inserted into a powered
system.
Small size, low installed cost, low power consumption, and short
propagation delays make the Si840x family the optimum solution for
isolating I
2
C and SMBus serial ports.
