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

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.
