General Description
The MAX9075/MAX9077 single/dual comparators are optimized for +3V and +5V single-supply applications. These comparators have a 580ns propagation delay and consume just 3µA per comparator. The combination of low-power, single-supply operation down to +2.1V, and ultra-small footprint makes these devices ideal for all portable applications.
The design of the output stage limits supply-current surges while switching (typical of many other compara­tors), minimizing power consumption under dynamic conditions. Large internal push-pull output drivers allow rail-to-rail output swing with loads up to 2mA, making these devices ideal for interface with TTL/CMOS logic.
The MAX9075 single comparator is available in 5-pin SC70 and SOT23-5 packages, while the MAX9077 dual comparator is available in 8-pin SOT23-8 and SO packages.

, unless otherwise noted. Typical values are at TA= +25°C.) (Note 1)
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
Note 1: All devices are 100% production tested at TA= +25°C. All temperature limits are guaranteed by design. Note 2: Inferred from CMRR. Either input can be driven to the absolute maximum limit without output inversion, as long as the other
input is within the input voltage range.
Note 3: Guaranteed by design.
