ABSOLUTE MAXIMUM RATINGS

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

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.
