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)

 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. Applications

 Cellular telephones

 Alarm and security systems

 Personal Digital assistants
