MAX9107EKA+T 

komparatory , DC=2008 , SOT23-8
The MAX9107/MAX9108/MAX9109 dual/quad/single, high-speed, low-power voltage comparators are designed for use in systems powered from a single 5V supply. Their 25ns propagation delay [with 10mV input overdrive] is achieved with a power consumption of only 1.75mW per comparator. The wide input common-mode range extends from 200mV below ground to within 1.5V of the positive supply rail.
