COMMENT
Stresses above those listed under “Absolute Maximum
Ratings” may cause permanent damage to the device.
This is a stress rating only; functional operation of the
device (at these or any other conditions above those
listed in the operational sections of this specification) is
not implied. Exposure to absolute maximum rating con-
ditions for extended periods may affect device reliability.

D.C. OPERATING CHARACTERISTICS
(Over the recommended operating conditions unless otherwise specified.)
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 nonvolatile write cycle; t
WC
after a stop that initiates
a nonvolatile cycle; or 9 clock cycles after any start that is not followed by the correct Device Select Bits in the Slave Address Byte.
