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

(1) This is not a supply pin, the substrate is attached to this
pad using conductive die attach material. There is no
electrical or mechanical requirement to solder this pad.
However, if it is soldered, the solder land must remain
floating or be connected to V
