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.
(2) The device goes into Standby: 200ns after any stop, except those that initiate a high voltage write cycle; t_WC 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.
(3) V_IL Min. and V_IH Max. are for reference only and are not tested.
(4) At 25°C, V_CC = 3V
(5) See ordering information for standard programming levels. For custom programmed levels, contact factory.
(6) Based on characterization data.
