3 Description
The LV device family consists of single, dual and quad
independent voltage comparators that operate from
a wide supply voltage range. The LV devices can
drop-in replace the standard TL331, LM2xx, LM3xx
and LM290x comparator family in low voltage (≤ 5
V) applications for improved performance and added
features.
The LV devices include a Power-On-Reset (POR)
feature to make sure the output is in a High-Z state
until the minimum supply voltage has been reached to
prevent output transients during power-up and powerdown.
The family also feature Rail to Rail inputs that
can go up to 6 V without damage or phase inversion.
The LV devices are specified for the temperature
range of -40°C to +125°C, which covers the ranges
of the TL331, LM2xx, LM3xx and LM290x comparator
families.
