... SDAI and V + must be SDAI is internally clamped to 6V (5.5V minimum). SDAO (Pin 8, LTC4151-1 Only): Inverted Serial Bus Data Output. Open-drain output used for sending data back to the master controller or acknowledging a write operation. Data is inverted for convenience of optoisolation. An external pull-up resistor or current source is required. ...

... Two three-state pins, ADR0 and ADR1, IN are used to decode nine device addresses (see Table 1). The LTC4151 features a single SDA pin to handle both input data and output data, while the LTC4151-1 provides separate SDAI (input) and SDAO (inverted output) pins to facilitate optoisolation.

... The transmitter always releases the SDA line during the acknowledge clock pulse. The LTC4151/LTC4151-1 pull the SDA line low on the 9th clock cycle to acknowledge receipt of the data. If the slave fails to acknowledge by leaving SDA high, then the master can abort the transmission by generating a Stop condition ...
