ABSOLUTE MAXIMUM RATINGS  
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.  
Temperature Under Bias.................. -65˚C to +135˚C  
Storage Temperature....................... -65˚C to +150˚C  
Voltage on any pin with respect to ground-1.0V to 7.0V  
DC Output Current .............................................5 mA  
Lead Temperature (Soldering, 10 Seconds) .... 300˚C

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.  
(2) The device enters the Program state 200nS after a stop ending a write operation and continues for t
