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-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 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 power-

down. 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-Q1, LM2xx-Q1, LM3xx and LM290x-Q1

comparator families.
