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
Address Byte are incorrect; 200nS after a STOP ending a read operation; or t
WC
after a STOP ending a write operation.
Notes: 1. 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.
Notes: 1. Current through external pull up resistor not included.
