NCX2202
Low voltage comparator; open-drain output
Rev. 5 — 30 October 2012
Product data sheet
1. General description
The NCX2202 is a single low voltage, low power, comparator with open-drain output.
The NCX2202 has a very low supply current of 6
A
and is guaranteed to operate at a low
voltage of 1.3 V and is fully operational up to 5.5 V. These characteristics make the 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 6
A
(typical)
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
