NCX2222 Low voltage comparator open-drain output Rev. 1 20 December 2012 Product data sheet 1. General description The NCX2222 provides a dual, low voltage, low-power comparator with open-drain outputs. The NCX2222 has a very low supply current of 5 A per comparator and is guaranteed to operate at a low voltage of 1.3 V. It is fully operational up to 5.5 V which makes it convenient for use in both 3.0 V and 5.0 V systems. 2. Features and benefits Wide supply voltage range from 1.3 V to 5.5 V (functional operating range) Rail-to-rail input/output performance Very low supply current of 5 A (typical) per comparator Very low-power consumption No phase inversion with overdriven input signals Internal hysteresis Propagation delay of 0.8 s (typical) ESD protection: HBM JESD22-A114F Class 1C. Exceeds 1500 V CDM JESD22-C101E exceeds 1000 V Multiple package options Specified from 40 Cto+85 C 3.
