Linear Technology LTC4301L
the LTC4301L SDAIN and SCLIN pins are compatible with systems with pull-up voltages as low as 1V. When the connection is made, the LTC4301L provides bidirectional buffering, keeping the backplane and card capacitances isolated. When driven low, the CS input pin allows the part to connect after a stop bit or bus idle occurs.| Part No. | LTC4301L |

In addition, Control circuitry prevents the backplane from being connected to the card until a stop bit or a bus idle is present.
