The MAX907/MAX908/MAX909 are dual/quad/single,high-speed, ultra-low-power voltage comparatorsdesigned for use in systems powered from a single+5V supply; the MAX909 also accepts dual ±5V supplies.Their 40ns propagation delay (with 5mV inputoverdrive) is achieved with a power consumption ofonly 3.5mW per comparator. The wide input common-moderange extends from 200mV below ground (belowthe negative supply rail for the MAX909) to within 1.5Vof the positive supply rail.

Because they are micropower, high-speed comparatorsthat operate from a single +5V supply and includebuilt-in hysteresis, these devices replace a variety ofolder comparators in a wide range of applications.MAX907/MAX908/MAX909 outputs are TTL-compatible,requiring no external pullup circuitry. All inputs and outputscan be continuously shorted to either supply railwithout damage. These easy-to-use comparators incorporateinternal hysteresis to ensure clean output switchingeven when the devices are driven by a slow-movinginput signal.

The MAX909 features complementary outputs and anoutput latch. A separate supply pin for extending theanalog input range down to -5V is also provided.

The dual MAX907 and single MAX909 are available in8-pin DIP and SO packages, and the quad MAX908 isavailable in 14-pin DIP and SO packages. These comparatorsare ideal for single +5V-supply applicationsthat require the combination of high speed, precision,and ultra-low power dissipation.
