ELECTRICAL CHARACTERISTICS—3V OPERATION (continued)

(V+ = 3V, V- = GND = 0V, TA = TMIN to TMAX, unless otherwise noted. Typical values are at TA = +25°C.) (Note 1)

Note 1: The MAX972EBL is 100% tested at TA = +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 1M

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

A faster response time is achieved with a smaller RC.
