Note 1 ââAbsolute Maximum Ratingsââ are those values beyond which the safety of the device cannot be guaranteed Except for ââOperating Temperature Rangeââ
they are not meant to imply that the devices should be operated at these limits The table of ââElectrical Characteristicsââ provides conditions for actual device
operation
Note 2 Unless otherwise specified min max limits apply across the 0 C to a70 C temperature range for the DS8906
Note 3 All currents into device pins shown as positive out of device pins as negative all voltages referenced to ground unless otherwise noted All values shown
as max or min on absolute value basis
