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 dropin
replace the standard TL331-Q1, LM2xx, LM3xx and
LM290x-Q1 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 ensures 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 6V 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-Q1, LM2xx-Q1, LM3xx and LM290x-Q1
comparator families.
