Application information 13.1 Operating description The NCX2220 is a dual low voltage low power comparator. This device is designed for rail-to-rail input and output performance. This device consumes only 5 A per comparator of supply current while achieving a typical propagation delay of 0.8 s at a 20 mV input overdrive. This comparator is guaranteed to operate at a low voltage of 1.3 V up to 5.5 V. The common-mode input voltage range extends 0.1 V beyond the upper and lower rail without phase inversion or other adverse effects. This device has a typical internal hysteresis of 9.0 mV. This allows for greater noise immunity and clean output switching. 13.2 Output stage The NCX2220 has a complementary P and N Channel output stage that has capability of driving a rail-to-rail output swing with a load ranging up to 5.0 mA. It is designed such that shoot-through current is minimized while switching. This feature eliminates the need for bypass capacitors under most circumstances.
