Si840x 2 BIDIRECTIONAL I C ISOLATORS WITH UNIDIRECTIONAL DIGITAL CHANNELS Features Independent, bidirectional SDA and 60-year life at rated working voltage SCL isolation channels High electromagnetic immunity Open drain outputs with 35 mA Wide operating supply voltage sink current 3.0 to 5.5 V 2 Wide temperature range Supports I C clocks up to 1.7 MHz 40 to +125 C max Unidirectional isolation channels support additional system signals Transient immunity 25 kV/s (Si8405) RoHS-compliant packages Up to 2500 V isolation SOIC-8 narrow body RMS UL, CSA, VDE recognition SOIC-16 narrow body Applications 2 Motor Control Systems Isolated I C, SMBus Hot-swap applications Isolated digital power supply Intelligent Power systems communications Power over Ethernet Description The Si840x series of isolators are single-package galvanic isolation 2 solutions for I C and SMBus serial port applications. These products are Ordering Information: based on Skyworks Solutions proprietary RF isolation technology and offer See page 25. 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 2 isolating I C and SMBus serial ports.
