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.

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

13. 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).
13.3 Zero-crossing detector
Figure 14 shows the NCX2222 configured as a zero-crossing detector.

third party customer(s). Customer is responsible for doing all necessary
testing for the customer’s applications and products using NXP
Semiconductors products in order to avoid a default of the applications and
the products or of the application or use by customer’s third party
customer(s). NXP does not accept any liability in this respect.
Limiting values — Stress above one or more limiting values (as defined in
the Absolute Maximum Ratings System of IEC 60134) will cause permanent
damage to the device. Limiting values are stress ratings only and (proper)
operation of the device at these or any other conditions above those given in
the Recommended operating conditions section (if present) or the
Characteristics sections of this document is not warranted. Constant or
repeated exposure to limiting values will permanently and irreversibly affect
the quality and reliability of the device.
