.
Note 2: The outputs are guaranteed to be in the correct logic state down to V
CC
= 1V.
Note 3: Measured with MR and MARGIN unconnected.
Note 4: The minimum and maximum specifications for this parameter are guaranteed by using the worse case of the SRT current
and SRT threshold specifications. Do not set the reset timeout period to more than 1.12s.
Note 5: Amount of time required for logic to lock/unlock outputs from margin testing
