RESPONSE TIME (4)

(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; not production tested.

(3)

See the Comparator Maximum Input Voltage Range section in the Application and Implementation.

(4)

The comparator response time specified is the interval between the input step function and the instant when the output crosses 1.4 V.
