(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 1 .
(2) Specified by design.
(3) See the Comparator Maximum Input Voltage Range section in the Applications Information .
(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) RESET input has an internal 2M Ω (typical) pull-down. Leaving 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.
