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 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, LM2xx, LM3xx and LM290x comparator

families.
