MAX971 Maxim, MAX971 Datasheet - Page 4

• Manufacturer Part Number: MAX971
• Description: The MAX971–MAX974 and MAX981–MAX984 single/dual/quad low-voltage comparators feature the lowest power consumption available
• Manufacturer: Maxim

ELECTRICAL CHARACTERISTICS—3V OPERATION (continued)
(V+ = 3V, V- = GND = 0V, T
Ultra-Low-Power, Open-Drain,
Single/Dual-Supply Comparators
Note 1: The MAX972EBL is 100% tested at T
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 pullup and the 100pF capacitive load, based on three time constants.
