TL3x1LV, LM393LV, LM339LV & LM393LV-Q1 Comparators

Texas Instruments TL3x1LV, LM393LV, LM339LV, and LM393LV-Q1 Comparators are two (LM393LV/LM393LV-Q1) or four (LM339LV/LM339LV-Q1) independent voltage comparators that are designed to operate from a wide range of supply voltages. The LM393LV/LM393LV-Q1/LM339LV/LM339LV-Q1 can drop-in replace the standard LM2x, LM3x, and LM290x comparator family in low voltage (≤5V) applications for improved performance and added features.
