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.
