3 Description

The LV device family consists of two (LM393LV-Q1),

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 power-

up and power-down.

These comparators also feature no output phase

inversion and 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.
