(1) Hysteresis refers to the threshold (the threshold specification applies to a rising edge of a noninverting input) of a falling edge on the
(2) Specified by design; not production tested.

(4) The comparator response time specified is the interval between the input step function and the instant when the output crosses 1.4V.
(5) The CMP1 RESET input has an internal 2M
(6) The Comparator 2 delay applies to both rising and falling edges of the comparator output.
