    Hi Surampudi,

    I recommend using the TCA9511A, as the TCA4311A has a major errata which is the "missing ACK". 

    The TCA9511A is p2p and drop-in to the TCA4311A. 

    The TCA9511A is a buffer and not an I2C target device. The timing requirements must be met by the system level design which is a factor of the bus capacitance and pull-up resistor selection. 

    Data hold and data set-up times are not required by the TCA9511A since this device is a buffer and not a target device. 

    Maximum junction temperature for TCA9511A is TJ(max) = 130 C

    Regards,

    Tyler
