Notes: 1. The device enters the Active state after any START, and remains active until: 9 clock cycles later if the Device Select Bits in the Slave
Address Byte are incorrect; 200nS after a STOP ending a read operation; or t_WC after a STOP ending a write operation.
Notes: 2. The device goes into Standby: 200nS after any STOP, except those that initiate a high voltage write cycle; tWC after a STOP that initiates a
high voltage cycle; or 9 clock cycles after any START that is not followed by the correct Device Select Bits in the Slave Address Byte.
Notes: 3. Current through external pull up resistor not included.
Notes: 4. V_IN = Voltage applied to input pin.
Notes: 5. V_OUT = Voltage applied to output pin.
Notes: 6. See “ORDERING INFORMATION” on page 30.
Notes: 7. V_IL Min. and V_IH Max. are for reference only and are not tested
