Response Time
(low-to-high transition) (Note 2)
Note 1:
MAX974/MAX984 comparators work below 2.5V; see
Low-Voltage
Operation section for more details.
Note 2:
Low-to-high response time is the result of the 1M
Ω
pull-up and the 100pF capacitive load, based on three time constants.
A faster response time is achieved with a smaller RC.
