ABSOLUTE MAXIMUM RATINGS
Temperature Under Bias.................. -65C to +135C
Storage Temperature....................... -65C to +150C
Voltage on any pin with respect to ground-1.0V to 7.0V
DC Output Current .............................................5 mA
Lead Temperature (Soldering, 10 Seconds) ....300C
Stresses above those listed under “Absolute Maximum
Ratings” may cause permanent damage to the device.
This is a stress rating only and the functional operation
of the device at these or any other conditions above
those indicated in the operational sections of this
specification is not implied. Exposure to absolute max-
imum rating conditions for extended periods may
affect device reliability.
DC OPERATING CHARACTERISTICS
(Temperature = -40°c to +85°c, unless otherwise stated.)
Notes:
(1)
The device enters the Active state after any start, and remains active: for 9 clock cycles if the Device Select Bits in the Slave
AddressByte are incorrect or until 200nS after a stop ending a read or write operation.
The device enters the Program state 200nS after a stop ending a write operation and continues for t
