Aside from providing I²C isolation, the LTC4310’s built-in rise time accelerators provide strong pull-up currents on SCL and SDA rising edges to meet I²C rise time specifications for heavily loaded busses. Hot Swap™ circuitry prevents data corruption when a card is inserted or removed from a live bus. A stuck bus disconnect and recovery feature attempts to free the card if the bus is stuck low for more than 37ms. In addition, the LTC4310 is equipped with a digital output pin to indicate I²C communications have been established, an enable pin to allow communication or to set the device in a very low shutdown current mode, ±5kV HBM ESD protection, and thermal shutdown. Both versions of the LTC4310 are specified over the commercial and industrial temperature ranges and offered in a 10-lead MSOP and tiny 3mm x 3mm DFN-10 package.
