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 μA 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 μA (typical) per comparator
Very low-power consumption
No phase inversion with overdriven input signals
Internal hysteresis
Propagation delay of 0.8 μs (typical)
ESD protection:
HBM JESD22-A114F Class 3A. Exceeds 2000 V
CDM JESD22-C101E exceeds 1000 V
Multiple package options
Specified from 40 °C to +85 °C
3. Applications
Cellular telephones
Alarm and security systems
Personal Digital assistants
