D.C. OPERATING CHARACTERISTICS
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
Notes: 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
