3 Description

The LV device family consists of two (LM393LV), or

four (LM339LV), 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 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 comparator families.
