3 Description

The LV device family consists of two (LM393LVQ1),

or four (LM339LV-Q1), independent voltage

comparators that are designed to operate from a wide

range of supply voltages. The LV devices can drop-in

replace the standard 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 that ensures the output is in a High-Z state

until the minimum supply voltage has been reached.

This prevents output transients during system powerup

and power-down.

These comparators also feature Rail to Rail inputs

and no output phase inversion with inputs that can

go up to 6V without damage. This makes this

family of comparators well suited for precision voltage

monitoring in harsh, noisy environments.

The LV devices are specified for the temperature

range of -40°C to +125°C, which covers the

temperature ranges of all the LM2xx, LM3xx and

LM290x-Q1 comparator families.
