(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 1.4V.

(5) RESET input has an internal 2MΩ (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.
