ANALOG DEVICES LTC4310CDD-2#PBF

LTC4310CDD-2#PBF is a hot-swappable I²C isolator that provides bidirectional I²C communications between two I²C buses whose grounds are isolated from one another. It encodes I²C bus logic states into signals that are transmitted across an isolation barrier to another LTC4310. The receiving LTC4310 decodes the transmission and drives its l²C bus to the appropriate logic state. The isolation barrier can be bridged by an inexpensive Ethernet, or other transformer, to achieve communications across voltage differences reaching thousands of volts, or it can be bridged by capacitors for lower voltage isolation. The LTC4310-2 is intended for 400KHz I²C systems. Rise time accelerators provide strong pull-up currents on SCL and SDA rising edges to meet rise time specifications for heavily loaded systems. Application includes isolated I²C, SMBus and PMBus interfaces, isolated power supplies, positive-to-negative Rail communications, power-over-ethernet.
