Ultra-Low-Power, Open-Drain,

Single/Dual-Supply Comparators

ELECTRICAL CHARACTERISTICS—3V OPERATION (continued)

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 1M

Ω pullup and the 100pF capacitive load, based on three time constants.

A faster response time is achieved with a smaller RC.
