Electrical Characteristics
Note 2: “Absolute Maximum Ratings” are those beyond which the safety of the device cannot be guaranteed. They are not meant to imply that the device should
be operated at these limits. The tables of “Electrical Characteristics” provide conditions for actual device operation.
Note 3: All currents into device pins are positive; all currents out of device pins are negative. All voltages are referenced to device ground unless otherwise specified.
Note 4: All typicals are given for V
Note 5: Derate linearly at 11.1 mW/˚C to 570 mW at 70˚C.
Note 6: All limits for which Note 5 is applied must be derated by 10% for DS3695T and DS3696T. Other parameters remain the same for this extended temperature
range device (−40˚C
