NCX2220 Low voltage comparator Rev. 4 27 June 2012 Product data sheet 1. General description The NCX2220 provides a dual low voltage low power comparator. The NCX2220 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 this device 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 3A. Exceeds 2000 V CDM JESD22-C101E exceeds 1000 V Multiple package options Specified from 40 Cto+85 C 3. Applications Cellular telephones Alarm and security systems Personal Digital assistantsNCX2220 NXP Semiconductors Low voltage comparator 4. Ordering information Table 1.
