(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) V
ID
refers to the differential voltage at the comparator inputs.
(4) Open-drain output can be pulled to the range of +2.7V to +18V, regardless of V
S
.
(5) The comparator response time specified is the interval between the input step function and the instant when the output crosses 1.4V.
(6) The RESET input has an internal 2MΩ (typical) pull-down. Leaving RESET open results in a LOW state, with transparent comparator
operation.
