NCX2222

Low voltage comparator; open-drain output

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

3. Applications

 Cellular telephones

 Alarm and security systems

 Personal Digital assistants

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 V_EEwith a load ranging up to 5.0 mA (see Figure 13).

Please consult the most recently issued document before initiating or completing a design.

The term ‘short data sheet’ is explained in section “Definitions”.

The product status of device(s) described in this document may have changed since this document was published and may differ in case of multiple devices. The latest product status

information is available on the Internet at URL http://www.nxp.com.

Suitability for use — NXP Semiconductors products are not designed,

17.2 Definitions

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.

Draft — The document is a draft version only. The content is still under

internal review and subject to formal approval, which may result in

modifications or additions. NXP Semiconductors does not give any

representations or warranties as to the accuracy or completeness of

information included herein and shall have no liability for the consequences of

use of such information.

Short data sheet — A short data sheet is an extract from a full data sheet

with the same product type number(s) and title. A short data sheet is intended

for quick reference only and should not be relied upon to contain detailed and

full information. For detailed and full information see the relevant full data

sheet, which is available on request via the local NXP Semiconductors sales

office. In case of any inconsistency or conflict with the short data sheet, the

full data sheet shall prevail.

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.

Product specification — The information and data provided in a Product

data sheet shall define the specification of the product as agreed between

NXP Semiconductors and its customer, unless NXP Semiconductors and

customer have explicitly agreed otherwise in writing. In no event however,

shall an agreement be valid in which the NXP Semiconductors product is

deemed to offer functions and qualities beyond those described in the

Product data sheet.

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.

17.3 Disclaimers

Limited warranty and liability — Information in this document is believed to

be accurate and reliable. However, NXP Semiconductors does not give any

representations or warranties, expressed or implied, as to the accuracy or

completeness of such information and shall have no liability for the

consequences of use of such information. NXP Semiconductors takes no

responsibility for the content in this document if provided by an information

source outside of NXP Semiconductors.

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.

In no event shall NXP Semiconductors be liable for any indirect, incidental,

punitive, special or consequential damages (including - without limitation - lost

profits, lost savings, business interruption, costs related to the removal or

replacement of any products or rework charges) whether or not such

damages are based on tort (including negligence), warranty, breach of

contract or any other legal theory.

Terms and conditions of commercial sale — NXP Semiconductors

products are sold subject to the general terms and conditions of commercial

sale, as published at http://www.nxp.com/profile/terms, unless otherwise

agreed in a valid written individual agreement. In case an individual

agreement is concluded only the terms and conditions of the respective

agreement shall apply. NXP Semiconductors hereby expressly objects to

applying the customer’s general terms and conditions with regard to the

purchase of NXP Semiconductors products by customer.

Notwithstanding any damages that customer might incur for any reason

whatsoever, NXP Semiconductors’ aggregate and cumulative liability towards

customer for the products described herein shall be limited in accordance

with the Terms and conditions of commercial sale of NXP Semiconductors.

Right to make changes — NXP Semiconductors reserves the right to make

changes to information published in this document, including without

limitation specifications and product descriptions, at any time and without

notice. This document supersedes and replaces all information supplied prior

to the publication hereof.
