General Description

The LV device family consists of single, dual and quad independent voltage comparators that operate from a wide supply voltage range.

The LV devices can drop-in replace the standard TL331, LM2xx, LM3xx and LM290x comparator family in low voltage (≤ 5 V) applications for improved performance and added

Key Features

1.65 V to 5.5 V supply range.
Rail-to-Rail input with Failsafe.
Low input offset voltage 400 μV typical.
600ns typical propagation delay.
Low quiescent current 25 µA/Ch typical.
Low input bias current 5 pA typical.
Open-drain output.
Full -40°C to +125°C temperature range.
Power-On-Reset (POR) for known start-up.
2 kV ESD protection.
Improved replacement for TL331, LM393 & LM339 family for VCC ≤ 5.
