, unless otherwise noted. Typical values are at T

= +25°C.) (Note 1)
Note 1: The MAX972EBL is 100% tested at T
A
= +25°C. Temperature limits are guaranteed by design.
Note 2: MAX974/MAX984 comparators work below 2.5V; see Low-Voltage Operation section for more details.
Note 3: Low-to-high response time is the result of the 1MΩ pullup and the 100pF capacitive load, based on three time constants.
A faster response time is achieved with a smaller RC.
