Note 1: Devices are tested at T_A = +25°C and guaranteed by design for T_A = T_MIN to T_MAX.
Note 2: The outputs are guaranteed to be in the correct logic state down to V_CC = 1V.
Note 3: Measured with WDI, MARGIN, and MR unconnected.
Note 4: The minimum and maximum specifications for this parameter are guaranteed by using the worst case of the SRT ramp cur-
rent and SRT threshold specifications.
Note 5: Guaranteed by design and not production tested.
Note 6: Amount of time required for logic to lock/unlock outputs from margin testing.
