(1) Hysteresis refers to the threshold (the threshold specification applies to a rising edge of a noninverting input) of a falling edge on the noninverting input of the comparator; refer to Figure 6-1.
(2) Specified by design; not production tested.
(3) See the Section 7.3.5 section in the Section 8.
(4) The comparator response time specified is the interval between the input step function and the instant when the output crosses 1.4 V.
(5) The CMP1 RESET input has an internal 2-MΩ (typical) pulldown. Leaving the CMP1 RESET open results in a LOW state, with transparent comparator operation.
(6) The Comparator 2 delay applies to both rising and falling edges of the comparator output.
