open-in-new Find other Comparators

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 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 comparator families.
