Application information 13.1 Operating description The NCX2222 is a dual, low voltage, low-power comparator with open-drain output. This device is designed for use with a pull-up resistor to define the output switching levels. 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. Figure 11 and Figure 12 show propagation delay with various input overdrives. 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 which allows for greater noise immunity and clean output switching. 13.2 Output stage The NCX2222 has an N-channel output stage that has the capability of sinking the output to VEE with a load ranging up to 5.0 mA (see Figure 13).
