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 C to +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).

Product data sheet
Suitability for use — NXP Semiconductors products are not designed,
authorized or warranted to be suitable for use in life support, life-critical or
safety-critical systems or equipment, nor in applications where failure or
malfunction of an NXP Semiconductors product can reasonably be expected
to result in personal injury, death or severe property or environmental
damage. NXP Semiconductors and its suppliers accept no liability for
inclusion and/or use of NXP Semiconductors products in such equipment or
applications and therefore such inclusion and/or use is at the customer’s own
risk.
Applications — Applications that are described herein for any of these
products are for illustrative purposes only. NXP Semiconductors makes no
representation or warranty that such applications will be suitable for the
specified use without further testing or modification.
Customers are responsible for the design and operation of their applications
and products using NXP Semiconductors products, and NXP Semiconductors
accepts no liability for any assistance with applications or customer product
design. It is customer’s sole responsibility to determine whether the NXP
Semiconductors product is suitable and fit for the customer’s applications and
products planned, as well as for the planned application and use of
customer’s third party customer(s). Customers should provide appropriate
design and operating safeguards to minimize the risks associated with their
applications and products.
NXP Semiconductors does not accept any liability related to any default,
damage, costs or problem which is based on any weakness or default in the
customer’s applications or products, or the application or use by customer’s
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.
