ELECTRICAL CHARACTERISTICS (continued)
(V
Note 1: The minimum operating voltage is 2.65V; however, the device is guaranteed to operate down to its preset reset threshold.
Note 2: Pulling RESET IN/INT below 60mV selects internal threshold mode and connects the internal voltage divider to the reset
Note 3: The Chip-Enable Propagation delay is measured from the 50% point at CE IN to the 50% point at CE OUT.
